What I will be describing is one made of tag board. Tag board, 150 lb weight paper, is available at paper, art or office supply stores. There is a limited life span on one made of this material, however it is extremely inexpensive, lightweight, very functional and useful as a basic design for those skilled enough to make one out of a more durable material.

Required materials:

• 4-inch by 22-inch strip of tag board
• 3-inch by 12-inch strip of tag board
• 1-1/2 inch by 10-inch strip of tag board
• Small roll of drafting or artist tape (it holds but does not tear paper when removed)
• Medium point black ink pen
• One small paper clip

To start, fold the 4-inch by 22-inch strip of tag board in half, creasing the fold. This is so it will fit in your pack. You want to do this first to avoid distorting the measurements.

Lay the 1-1/2 inch strip on the very end of the 4-inch strip at a 90-degree angle to the 4-inch strip to form a T-shape; mark the 4-inch strip at the bottom of the 1-1/2 inch strip. This is where you will start marking your measurement lines. See Figure A.
