One of my friends sent me a few strips of fleece and yesterday I made a blanket for my little nephew.
I stitched them with long stitches and the widest seam allowances.
I pieced the blocks and finger pressed the seam allowances open then I stitched them down. No bulky seam allowances on the back side.
Some of the blocks distorted more than others so that I adjusted the size of all blocks.
Instead of adding binding I just zigzaged twice the edges together with wide and dense stitches. While stitching I stretched the edges and I got this nice waved effect. And there are just a few rows of stitches for keeping the layers together.
