This My way: When I retired I had Lots of Bandage/wound care supplies from my work. I decovered That the Paper Tape Will stick to the Fabric, Won't come off,Won't leave a sticky mess,and I have even Wash it One time and IT was Still there! and Still No problem!! ALL I do IS Wright the INFO on the TAPE with Sharpe BEFORE You PUT It on the Fabric and Your Good to go!! Label your blocks say: this block A-1 and stack that row all up atogether, next row; B-2 stack all them up and so on.....
