/diy/ - Do It Yourself

I cut a 1" seam allowance on the edge that gets gathered, then do a medium zig zag over a long piece of dental floss in the seam allowance, about a quarter inch from the seamline. Pin a measuring tape to the ironing board in the finished length you need for the gathered edge. Anchor the floss on one end by wrapping it around a pin in the fabric. Pin that end to the ironing board at the start of the measuring tape. Gently slide the fabric along the dental floss until the gathered edge is the correct length. Put a pin in the the end of the fabric and anchor the floss to the pin. Distribute the fullness evenly then run a second medium zigzag or long straight stitch over the first narrow zigzag in the seam allowance. Pull out the dental floss, then baste the gathered fabric to whatever you're sewing it to along the seamline. Trim away the excess seam allowance and sew in place permanently.
