Thanks so much for the tip about moleskin!! I went to Walmart and the pharmacist showed me where to find it (with the Dr. Scholl foot supplies).
This afternoon I cut a small long piece and placed it 1/4" all the way down from the "little foot" with the 1/4" side, and I can't tell you how wonderful it is!!!! It is thick enough to guide the strips right through and it makes my four-patch squares so easy to do!!!! I love it!!!
Thanks again, Lulie :D
