After laying out the blocks, I decided to add 22 more blocks to make the quilt bigger. I figured that I had the extra fabric so why not? Plus, I've noticed that dense machine quilting tends to make the quilt shrink. Have you noticed that?
Quilting shrinkage is not from the fabrics shrinking because you didn't pre-wash them or from the batting shrinking when the quilt is washed. Both not pre-washing fabrics or batting can create shrinkage, but there is also shrinking that can happen from dense machine stitching. With dense quilting, the stitches in effect "pull" at the fabrics and create shrinkage.
It's difficult to estimate just how much shrinking will occur from machine quilting, so I like to make the top a little bigger to account for the quilting shrinkage so that the quilt is large enough after quilting. For this quilt, I made an extra column and row, which meant an extra 22 blocks. In total, I pieced 132 blocks.
Now I've got a top ready for quilting.
