I’m taking part (albeit quite late to the party) in the McCalls Pattern Shirtdress Sew-Along. I’m making Kwik Sew 4155, from a lovely lightweight shirting from Gorgeous Fabrics (of course). After pre-washing my fabric, I saw that it was puckery along the selvages. That’s not at all unusual with woven fabrics. Because of the finishing of the fabric at the edges (to keep it from unraveling), the tension on the selvage threads is higher, which can cause some puckering:
Well, at a sit and sew with the wonderful couture teacher Susan Khalje, I learned a little trick to release that tension.
Simply make small cuts along the selvages. These cuts are about 1/4 inch deep in the case of this fabric, and spaced about every 2-3 inches. I did make a cut right at a pucker if it seemed pretty tight. I cut on a diagonal, but I don’t think it makes much of a difference if you cut perpendicular to the selvage. The picture below shows what it looks like after snipping, and I didn’t press it or otherwise flatten it out, so you can see what a difference it makes.
It only takes a few seconds to do, and it will make sure your fabric lays flat so you get an accurate cut close to the selvage.
This is closely related to the tip I wrote a while back on Trimming Your Knit Selvages. Same principle, and it will make your life a lot easier.
Shameless Plug Time: Speaking of Susan Khalje, if you ever have the opportunity to take a class with her, do it! Susan is a delightful person, a wonderful teacher and, as a professor at FIT said, “She sews a mean stitch.” One of my bucket list items is to go on her Paris Tour. I can’t do it this year because of a very big (!) family commitment at the end of the year, but hopefully soon! Full disclosure: Susan is a dear friend of mine, but she is one of the BEST sewing teachers out there, bar none.
HTH and happy sewing!
