Now that phase 1, making the playmat top, is complete, I am ready to think about quilting it. So, I made a quilting plan. Now that it's done, I’m not sure if I love it or if I will ever do it again, but I am happy with the finished product.
Because the mat is only 36" x 36", it was easy to pick out a backing. I just needed a yard of any 42" fabric. If I would have gotten it quilted, I would have needed 44" x 44" because the quilter needs 4 extra inches on each side of the backing and the batting. I would have needed to sew on 2-4" panels on the sides and would have bought 1 1/4 yards of fabric.
The main reason I do not like quilting it myself is because it is extremely time consuming and I can see every flaw. Next time I will pay to get it quilted!
I sewed lines 1/4" away from the sashing, and I stitched in the ditch around each number.
