Both of the quilts were really easy. The harmonic convergence is 4 fat quarters, sew in groups of 2, cut in strips sew together, you turn it and cut again and resew.
The pinwheel starts with 11 inch blocks with a border. You cut it into pinwheels and sew them together. You then add another border and recut it. You have a bunch of 6 inch square to make a small quilt(I did borders) and some other squares that will make small pinwheels. I haven't sewn them together yet. I have directions for both that I would share. PM me if you want them. You need a special ruler for the pinwheel. Easy to make from a square of plexiglass.
