Should I still pin it to muslin? I'm guessing that maybe that would help ensure that the layers stay flat. How about what stitch to use? I'm wondering if I could just use a running stitch if I were careful about the tension, or perhaps a backstitch to be stronger, or a whipstitch to help with fraying--but wouldn't that leave a lump, and would that even work for sewing the pieces onto a muslin background?
I feel like I really want to start using up fabric scraps from dd's wardrobe, but we're still at the stage where I have precious little time to use the machine...most of my projects are by hand in locations where the kids can play, or in the car when I'm not driving, etc., not so much in my sewing room. So, I'm leaning toward doing the entire quilt by hand. Everything I google only talks about quilting the pieces together by hand, but nothing about assembling the pieces without a machine. Thoughts? Links?
