Lisa, you make a good point about making only a few and testing each unit to make sure they're coming out right before sewing a whole bunch. And being new to quilting (this is only my sixth quilt and my 1st mystery quilt), I did stay within the confines of Bonnie's suggestions for fabric colors. Maybe once I've made a few more quilts, I'll be more comfortable substituting colors because I really did enjoy seeing the variations other quilters did.
