For the pre-folded tape method in my video, open the tape and place one raw edge against the quilt's raw edge. Start on the duck-cloth side so the final visible stitching can be on the cotton side. Leave a loose starting tail.
Clip the tape in place and sew along its first crease. Test this on your layered scrap first. The finished tape must cover the edge and the first stitch line when wrapped over.
At each corner, make a miter: a small diagonal fold that lets the tape turn neatly. The stopping point depends on your seam width, so do not copy a fixed one-inch stopping distance for every tape. Use the corner directions for your chosen binding method.
Leave about 10-“12 inches of the quilt edge unsewn near the starting point. Join the loose ends, then sew down that gap. Watch my demo at 7:11 and check the linked guide before cutting the tails.
Wrap the tape over the raw edge to the cotton side. Tuck the raw edge inside its fold. Clip it so the folded edge covers the first stitch line. Form a neat diagonal fold at each corner.
Sew close to the folded edge. I use a blanket stitch in the video. A straight stitch works too if it catches the folded edge all the way around. Check both sides for missed spots and sew them again.
For a different option, WeAllSew's quilt binding lesson explains folded quilt binding. Follow that method's own cut width and seam allowance rather than mixing its steps with packaged tape directions.
