1. Can anyone suggest how to get your blocks lined up perfectly at the joints without so much back tracking; fixing blocks that moved.
Glue baste the joins instead of pinning the joins. I do this at the ironing board. Align the seams as you want them, then put the tiniest dot of glue inside the seamline and press with the hot iron. I use Elmer's washable white glue. The glue washes out later or, if you need to open up the seam, comes apart if moistened with a drop of water from your fingertip.
