Pine
Pines is among the most commercially important genus of tree, valued for its timber and wood pulp throughout the world. Pine wood is widely used in high-value carpentry items such as furniture, window frames, paneling and floors. Pine is readily available at commercial lumberyards, being among the least expensive forms of lumber. Pine is light yellow to white with a reddish tinge. It darkens to an orange tint with age. The wood is soft and easily shaped with both hand and power tools, making it a very popular choice for wood craft.
Walnut
The Persian Walnut, and the Black Walnut and its allies, are important for their attractive timber, which is hard, dense, tight-grained and polishes to a very smooth finish. The colour ranges from creamy white in the sapwood to a dark chocolate colour in the heartwood. When kiln-dried, walnut wood tends toward a dull brown colour, but when air-dried can become a rich purplish-brown. Because of its colour, hardness and grain it is a prized furniture and carving wood. Walnut burls (or 'burrs' in Europe) are commonly used to create bowls and other turned pieces. Veneer sliced from walnut burl is one of the most valuable and highly prized by cabinet makers and prestige car manufacturers.
Oak
Oak has very attractive grain markings, particularly when quarter-sawn. Wide, quarter-sawn boards of oak have been prized since the Middle Ages for use in interior paneling of prestigious buildings such as the debating chamber of the British House of Commons in London, England, and in the construction of fine furniture. Today oakwood is still commonly used for furniture making and flooring, timber frame buildings, and for veneer production.
Oak is a very hard, strong, and durable wood. It is not easily worked when cured, and is thus not a good choice for the beginning wood crafter. However, in the hands of a skilled craftsman, it is an excellent choice, holding carving detail well over very long periods of time.
Cedar
The fine-grained, soft brittle pinkish- to brownish-red heartwood is fragrant, very light and very durable, even in contact with soil. Because of its rot resistance the wood is used for fence posts. Because the aromatic wood is avoided by moths it is in demand as lining for clothes chests and closets, often referred to as cedar closets and cedar chests. It was once a premier wood for pencils.
Cedar is available at some lumberyards, but is often located in a section of the store reserved for outfitting closets. It is more expensive than pine, but not out of reach of the budget-conscious Pathfinder. Its aroma alone make it well worth the added expense compared to pine, and it works just as easily. It is an excellent choice for the beginner.
Maple
Some of the larger maple species have valuable timber, particularly Sugar Maple in North America, and Sycamore Maple in Europe. Sugar Maple wood, often known as "hard maple", is the wood of choice for bowling pins, bowling alley lanes, pool cue shafts, drums, and butcher's blocks. Maple wood is also used for the production of wooden baseball bats, though less often than ash or hickory.
Some maple wood has a highly decorative wood grain, known as flame maple and quilt maple. This condition occurs randomly in individual trees of several species, and often cannot be detected until the wood has been sawn, though it is sometimes visible in the standing tree as a rippled pattern in the bark.
Maple is a very hard wood, and while that makes it difficult to work with hand tools, it also makes it a very good choice when fine carving details are desired. Because of its working difficulty, it is a wood better left to the experienced craftsman rather than the beginner.

Coping saws are very useful for removing bulk. A carving can often be roughed in with a coping saw, and once the shape is cut out, knives, chisels, and gouges can be used to clean it up and do the final shaping. Coping saw blades can be sharpened with a triangle file, though they are cheap enough that they ore more frequently replaced when dull.
The blade can be installed on the coping saw so that it cuts on either the pull stroke or the push stroke. Experiment to see which you like better. To make a cut, clamp the piece to a bench or hold it firmly with your free hand or knee. Align the blade with the pencil mark you have made which will guide the cut. Gently work the saw up and down to make the cut. You may have difficulty at first, and this does take a little practice to master. But once you have it down, it is not all that difficult. Follow the line until the cut is complete.

Take a piece of wood that is square with a thickness of at least 1/2 inch and draw the animal you want or use carbon paper to trace an existing picture of an animal. Be sure to leave the bottom edge of the board straight, as this will fasten to the flat part of the bookend. Use a coping saw to cut out the animal shape. Sand the board to make it smooth and remove all splinters. Once this part is ready, fasten it to the lower part of the bookend at a 90° angle using two wood screws. The screws should go through the horizontal bottom piece first, and then into the endgrain of the vertical piece (with the animal cut-out). Drill pilot holes before driving the screws or the boards will crack. The diameter of the drill bit should be equal to the diameter of the screw minus the threads. This can be estimated by holding the drill bit behind the screw. The threads should extend past the drill bit, but you should just barely be able to see the drill bit itself. Bore a countersink hole in the underside of the horizontal piece so that the screw will not extend past the surface of the board. When the holes are ready, drive the screws. At this point, you can paint, stain, or varnish the bookend. Once the finish is dry, glue a piece of plastic craft foam or felt to the bottom of the bookend to protect the bookshelf. The foam or felt should create a non-slip surface so the books will not cause the bookend to slide over.

Materials that you will need for this project include: 1/4 inch plywood (3 feet square), 1/2 inch block of wood (can be plywood or wood stock),* a coping saw, a sanding block, and any art materials that you wish to use to color the project once you have finished all other steps.*
- Note: Items marked with an "*" are not required for this project. You do not have to paint the project, but it will look much nicer if you do. Also, you can cut the stake part of this project below the design that you select. However, the finished project will not be as sturdy as one that uses the 1/2 inch block of wood.
Take your 1/4 inch plywood and draw (or trace with carbon paper) the design that you wish to use for this project. When you are finished drawing, take a coping saw and cut out your design. If you find that the plywood is tearing out excessively, put the coping saw away and get out a carton knife (or use a hooked blade on a pocket knife). Slice a V-groove around where the saw will cut. This cut should go straight down (90°) along the line, and angle in from the waste side. Next closely examine the teeth of the coping saw, and re-install the blade so that it cuts on the pull stroke rather than on the push stroke. You may notice that a saw always rips out on the side of the board that the cutting stroke exits. By using a knife to cut out around the line, there is nothing to tear out, but this only works if the blade cuts on the pull stroke.
Then, sand the edges gently to remove the excess wood particles that make the design rough and unfinished. Next, take your 1/2 inch block of wood and cut it to about 18 inches in length and cut one end to a point (it is best to make a 45 degree cut from both sides of the stake). Now, attach your design to the stake using wood glue, finishing nails, or wood screws.
- Note: If you are making the entire project from the 1/4 inch plywood, the stake extends from the bottom of the design anywhere from 12-18 inches. Do not cut the stake out separately, but cut down beyond the design to make the stake.
Finally, you may decorate your project with paint, if you wish. It would be best to put a water sealant on your project before placing it outside so that rain will not ruin it.

Woodburning is the art of decorating wood or other materials with burn marks resulting from the controlled application of a heated object such as a poker. It is also known as pokerwork or pyrography.
Pyrography means "writing with fire" and is the traditional art of using a heated tip or wire to burn or scorch designs onto natural materials such as wood or leather. Burning can be done by means of a modern solid-point tool (similar to a soldering iron) or hot wire tool, or a more basic method using a metal implement heated in a fire, or even sunlight concentrated with a magnifying lens.
This allows a great range of natural tones and shades to be achieved - beautiful subtle effects can create a picture in sepia tones, or strong dark strokes can make a bold, dramatic design. Varying the type of tip used, the temperature, or the way the iron is applied to the material all create different effects. Solid-point machines offer a variety of tip shapes, and can also be used for "branding" the wood or leather. Wire-point machines allow the artist to shape the wire into a variety of configurations, to achieve broad marks or fine lines. This work is time-consuming, done entirely by hand, with each line of a complex design drawn individually. After the design is burned in, wooden objects are often colored, sometimes boldly or more delicately tinted.
Light-colored hardwoods such as sycamore, beech and birch are most commonly used, as their fine grain is not obtrusive, and they produce the most pleasing contrast. However, other woods, such as pine or oak, are also used when required.
By far, the easiest option for meeting this requirement is to decorate a plaque. Blank, unfinished wooden plaques are readily available at craft stores. Begin by drawing your design on the wood with a pencil. You can then proceed to burn your design into the wood with the wood burning tool or with the sun and a magnifying glass. Choose a simple design for your first attempt, as this technique requires patience and persistence. Once the design is burned into the wood, it can be finished with varnish, tung oil, or lacquer.
The South American Division has developed an honor called Pyrography which is specifically about wood burning. Keep in mind, however, the patch token will not be easy to attain for anyone outside of that division.
