I will square up the sides after quilting. I even got the back pieced and it is about to go off to the long arm quilter.
It seems a little odd to spend all that time hand piecing this baby only to quilt it by machine. I briefly considered hand quilting, as several quilters whose progress I have followed online are doing with their versions. But after contemplating the backside of the top, I decided my hand quilting skills are not a match for the many seam allowances that need to be quilted. Here's a look at the back with papers removed:
The pieces are so tiny that the seam allowances often overlap, so that hand quilting stitches would have to go through two or three layers of fabric, and that's just the top, not including the batting and backing fabric. The only way around all the layers is to quilt inside the larger pentagons and diamonds only. So I decided to go with machine quilting. More experienced hand quilters may have no trouble with all the layers.
I'll be back with more on this quilt when it is truly finished, but in the meantime, I'm moving on to a "fast quilt" project.
