Stewyscrewy, I wasn't sure what she meant by keeping a finger between the fabric either until I just sat down and did 12 Drunkards Path blocks. It is a finger of your left hand. Seems like sometimes I had my index finger between the fabric and thumb on top and sometimes the opposite. I have about 150 DP blocks to go, so I'll probably have it figured out before long.
Brushandthimble and Gramalama9, did either of you have problems with the top or bottom fabric stretching out by the end as I did. If so, what did you do to correct it. I lost my receipt for the Curve Master and can't return it, so I would like to be able to use it without having to square up my blocks after sewing.
