|I groan when I read a pattern calling for a double-fold hem that involves first turning the raw edges under 1/4-inch. I usually change it to 3/8-inch, just so that it's not as difficult for me to measure and pin. But now that I have a serger - no problem! I just serge the raw edges (skimming the knife), and then I have a perfect 1/4-inch measure along the edge. I fold it to the edge of the serger threads and pin and press there, then fold again to whatever measurement is called for. This is going to make me much happier with 1/4-inch folds.
