I had a shoebox full of HST's( in assorted sizes) left from a quilt. I just couldn't make myself throw them out, so I put a a piece of batting for a design wall and started playing. I ended up with something similar to Maniac Quilter's photo with some of the HST's and tried out different designs with other sizes. I sewed each group together into block units, and will eventually join them together in a gypsy wife style quilt. (Once I've finished the Gypsy Wife quilt along and have some experience joining the non-uniform shapes.)
