1. Cut the sleeve 8½” wide x the exact width of your quilt. Fold the ends in twice (¼” and ¼” again) to finish each end of the sleeve. Stitch using a scant ¼” seam allowance.
Press the long sides of the sleeve so they meet in the center.
It helps to fold the sleeve in half lengthwise first and press to create a center crease.
When you press the sides to the center, you’ll press those creases out – they just give an easy guide without measuring or marking.
