|In the throes of sewing up the much reviewed KS wrap top, I found the common complaint was that the top gaped at the CF where the two layers met. I used a tip from the Palmer Pletsch "Fit for Real People" book. To stabilize the seam, I sewed stay tape on the seamline. In order to make the fit a bit more snug, cut the tape 1/8" shorter than the seamline and ease to fit. Unfortunately for all you Steam a Seam fans, this only works with sew in tape. I found that the two layers fit sung against my chest and did not gape open. This technique is also recommended in the P/P pant patterns for use on their pockets. I guess it would work on any bias edge.
