Projects Matching a print for my dress. It helps to lay the pieces together that will be sewed together Remember to allow for darts on each side of the zipper to match print. I like to make my own bias tape, which is cut on the bias then sprayed and ironed, make plenty First sew 1/8 inch from the neck edge, then lay the raw edge of the bias tape next to the stitches and sew in the crease. Finish the waistband and edge of zipper then baste first. Dampen the zipper then iron before you sew. I like to use the piece next to the selvage, easy to get a straight edge for long ties.
