Ready to bring the artist out in you!
I was recently given a table loom and, once I learn how it works, plan to weave with recycled neckties much as rag rugs are made. Mom used to cut up rags for rugs in as long a continuous strip as possible, and I plan to do much the same with ties. I'll keep you posted on the results!
When designing patchwork for a jacket, remember to consider the balance of color and pattern if you are not making identical or mirror image pieces. This especially matters when making the fronts. Design can balance vertically, horizontally (across the pieces), or diagonally. For a diagonal example, consider a pocket on one side balanced against a similar design on the opposite shoulder.
