I think this mini quilt holds the record of number of pieces for me. It's 14 x 14 and close to 700 pieces. I made the stars 3" with extra around the edges to avoid matching point.
These are paper pieced, and some of the pieces ended up only 1/8" wide. I graded all the seams to help them lay flat, and hand tacked a lot of the points together when assembling the stars.
