These are pieced blocks and I made these so long ago I don't remember if I back-stitched at the beginning of a seam or not, I think I did. They just seem not sturdy enough for me. Remember, it was my first attempt at piecing and the stitches were not the greatest. I cannot do hand piecing now due to arthritis and carpal tunnel, so I'm wondering, if I go back and machine stitch some of these seams, will I be more apt to finish this quilt? It's been a dilemma for too long now and I want to get this finished.
