Simple frame weaving looms can be made at home with inexpensive artists' stretcher bars (also called stretcher strips) and common household tools and materials. These looms produce quite acceptable results for making lace and weaving simple projects such as small home decor articles and plain tapestries. You can make large rectangular frame looms for weaving scarves or table runners and a variety of square looms that can be used over and over again for placemats, small apparel items and even rugs.
Calculate the size stretcher bars needed for the project. Add 6 inches to the width of the finished project and 10 inches to the length; purchase a set of stretcher bars for each. For example, a finished project that is 12 inches wide by 16 inches long would require a set of 18-inch stretcher bars and 26-inch stretcher bars.
Join the stretcher bars at the corners to form a frame. Place three staples crosswise where the bars join, making sure the frame is an even rectangle (or square) and not lopsided.
Mark the outer edges of the top and bottom bars beginning 1 inch from the inside and across the bars, stopping 1 inch before the other side. Make grooves in the edges at each mark with a hand saw. For thicker stretcher bars, make sure the grooves cover the entire outer edge. Sand the grooves and all rough edges.
Tie the cotton cord to the frame loom in the top left groove. Bring the cord down to the first bottom groove and wrap around the groove and up the back of the loom to the next groove in the top. Continue to wrap, keeping the cord tension taut, but not so tight that you cannot lift them for weaving. Be sure to place each cord in the grooves. There should now be two sets of cords on the loom. These vertical cords are the warp, the foundation of any weaving project.
Make the two sets of warp threads into one layer by working a length of string over each top thread and under each bottom thread at the bottom edge of the loom. Tie off the string at both sides. The loom is now ready for weaving.
