|I've never been satisfied with a rolled or narrow hem, as it doesn't start or end well, and it's often uneven in width.
Should work but doesn't: David Coffin's rolled hemmer. Claire Shaeffer's "The Complete Book of Sewing Shortcuts" method almost works. Everything I learned in junior high home ec: no. Pressing first just burns my fingers.
Today I finished a shirt for DH, KS # 2000, and the rolled hem from the pattern directions worked beautifully: overcast the bottom edge of the shirt, fold a narrow hem to the inside and stitch close to the inner edge.
I did the overcast on my regular Pfaff and pressed the narrow edge up before stitching. The beginning and end (faced and interfaced edges) and the shirttail curves were perfect, and definitely looked professional.
Even after laundering, that hem is still beautiful.
