Now that you mention it I do remember cutting the pieces in strips on the quilt I did with foundation piecing. I believe I cut each strip the width of the piece it was for. That might save on wasted fabric and I don't have a lot of this fabric since it is left over from another quilt.
I have 4 color ranges; green, blue, purple, and turquoise, with 5 shades of each. I hope there is enough with a total of 20 fabrics with each of them more or less than a fat quarter, probably. I went to Michael's at lunch yesterday and I picked up 4 of their little packets of 5 graduated colors, purple, green, blue and yellows, so if I get in a bind some of them are pretty close to what I already have
I'll try the strips on the next block.
