|Here is a technique that has been around for ages, but may be new to those of us just beginning to sew. It gives finished seams, inside and out, with just one line of stitching. I use it for short sleeves, some pants hems and home dec sewing like pillow cases.
Begin by measuring a hem twice as wide plus 3/4" as the finished hem. Press to the wrong side of the fabric/garment.
Unfold the hem and bring the bottom edge to the fold. Carefully fold the two layers over the top. You now have a fold facing you. Inside and tight to the fold is the original bottom edge. Press. Pin sparsely to maintain the integrity of the hem.
Stitch 1/4" from the fold along the entire length of the hem.
Press to set the stitches. Open the fabric, right side up, with the 1/4" ridge pointing up. Carefully press the ridge down toward the body of the garment/fabric.
You can sew another row of stitching 1/4" from the hem edge, if desired.
You now have a hem that looks as if it has been cuffed. The inside is completely finished and so are you! :~)
