I've made several quilts and for my current lap quilt I had just heard about basting. I believe the borders came out flatter by basting than ever before. They didn't stretch out of square. The walking foot really eased the fabric so I did not get any puckers. Also this quilt I only had to trim 1/8 inch just in some places. The best that has been with any other quilt. I'm sold on basting.
