I echo quilted 1/2" lines on the pomegranate. Inside the star, I echo quilted at 1" intervals. That turned out to not be the best choice, as it shows every little piecing error (and there are plenty of not-quite-perfect intersections). Another case of live and learn. I seem to have a lot of those.
Final dimensions of this mini is 19 1/4 inches square. Though it isn't, ahem, perfectly square. The pieced squares are finished at 1".
