Here are a few tips and pointers for making perfect hems and seams that lay flat, look great and are very easy.
Ironing is extremely important for hems as well as seams. Pressing either one helps it to lay flat for sewing or wearing. With a blouse side seam, for example, press open after stitching. The side seam will feel and look smooth during wear. Sometimes the fabric pieces cling together while you're trying to press them. Use a wooden ruler or another flat object to hold the seam open while pressing.
Seam binding is a big help when doing sheer fabrics. Make the seam and press open using a towel to prevent scorching. Place the binding tape over the seam and center it. Pin into place and stitch down both one edge of the binding tape. Do not yet remove pins. Stitch down the other side of the binding tape removing pins upon approach.
Binding tape can also be used on skirt or dress hems. Place the binding tape and fabrics right side together and stitch. Stitch the tape all the way around the edge of the skirt. Fold the tape behind the skirt fabric turning a quarter to a half-inch of fabric along with it. Measure, pin and iron. Stitch the edge of the binding tape from the backside. When finished, press again.
Tiny hemmed openings, like the armholes of a baby blouse, are difficult to pin and stitch. It's sometimes easier to do this by folding as you go along. Fold fabric under a quarter inch then fold over another quarter inch. Smooth flat with fingers. Sew a couple of stitches forward. Continue turning the fabric and pressing with fingers as you stitch around the armhole. When finished press well with iron.
