Even if you live in the country or far from a large town you may secure anything you wish by consulting one of the aeronautical magazines and writing to advertisers for illustrated lists. Most of the aeronautical supplies you will require are so light and small that they can be shipped by parcels post and it will surprise you to find how cheaply all such supplies are sold. In covering the planes some builders cut the cloth into seven strips, each 4' 6-1/2" long, and sew these together so that a piece a little over 20 feet long is formed. To reinforce the seams narrow strips 1-1/2" wide are sewed across the cloth and turned over to form a stout double thickness over each rib. While this method of construction is very strong, yet the difficulty in getting the seams even and the cloth free from wrinkles is very great, and is apt to discourage an amateur. A method which will serve every purpose is to cut the cloth into strips a little over four feet in length and glue the end of each strip around the front horizontal beams of each plane, and tack it in place with small copper tacks. Draw the other end back over the ribs and tack the edges of the strip to the ribs as you go along. In placing the tacks through the fabric a strip of narrow felt or tape should be placed under the tacks to prevent their tearing out; but this should be almost as narrow as the width of the tack-heads to prevent loose edges, and care should be taken to keep each piece of fabric very tight, smooth, and free from wrinkles as you tack it in position.
