Hey Ya'll! So I've been tweaking my muslin. Since I'm trying to mimic the piping in this Ralph Lauren Dress, I'm trying to make heads or tails of these cuff instructions. Any tips, cause I'm really lost. I'm doing sort of a "cuff interfacing" which is really just sandwiching two together with piping... and does this make any sense? Still, the instructions look like the cuff is the wrong side out in the 'how to' but the main illustration seems right.
