Lesson one: design several options.
What fun! I used EQ to make these Designer Pinwheel line drawings. Not only did it extend my knowledge of how to use EasyDraw in EQ, but it was much quicker than drawing the designs on paper. The objective was to design the patterns, without regard to potential difficulty of piecing. So at this stage, forget about how you'd construct the quilts.
I've narrowed it down to these four designs and would welcome feedback about your preferences. I won't tell you my favourite yet.
