i tried going ahead and doing the (clipping the edges) before sewing together once---what a nightmare that wound up being- it was very difficult to sew the blocks together-
might of course just been me---but i suggest you cut a couple blocks and sew them together and see how that part goes before you cut them all...just in case- i really wish i had tested first- because i never would have cut them all- but like i said could have just been my malfunction
