I even used two strands of variegated this time (vs. one solid and one variegated color). It really is an "anything goes" rug.
Over the years I have crocheted dozens and dozens of crocheted and knitted dishcloths, and many sets of pot holders. The leftovers simply were put in bags for a future project. To be honest, I am glad I kept them all.
Update: I found a possible store to sell these at. I am researching what I need (tax I.D., etc) to do it, and of course, I need many rugs made to do it.
