T-shirt rags make durable rugs from shirts that are too shabby to go on as clothing. My first t-shirt rug, woven more than 15 years ago, is still in the bathmat rotation for my family of four. T-shirt rags also weave up quickly. Even with an energetic, weighted beat, the doubled rags fill an inch every four or five picks.

A four shaft overshot pattern can be converted to double weave using 4 shafts, but using 8 shafts makes the threading easier. The threading can be repeated on shafts 5 through 8 in parallel as shown on the draft; shafts 1-4 for the top layer and 5-8 for the bottom layer. The treadling is paralleled as well with the left four tie-ups weaving the top layer and the right four tie-ups weaving the bottom layer.
