Example 1: traditional attachment on the pillowcase edge
Example 2: attaching the edging a few inches beyond the pillowcase edge and sewing down one side of the edging
Example 3: attaching the edging a few inches beyond the pillowcase edge and sewing down both sides of the edging--my method
This edging lies flat with no ironing needed, unlike Example 2, and doesn't take a beating in the washing machine unlike Example 1. Yes, it does take twice as long to attach the edging using this method, but the results are literally years of enjoying using your beautiful tatting without having to hand wash it.
