To join the ends of a quilt binding with a diagonal seam, you overlap the binding strips, unfold the ends, align them perpendicularly, mark a diagonal line across the overlap, sew along this line, and then trim the excess fabric.
Joining quilt binding with a diagonal seam creates a less bulky and more durable join compared to a straight seam. Here's how to achieve this neat finish:
After attaching your binding strip around most of your quilt edge, leave a gap of about 6-10 inches unstitched where you will join the ends.
Step 1: Overlap and Trim
Bring the two unsewn ends of the binding together. Overlap them by the exact width of your binding strip. For example, if your binding strip is cut 2.5 inches wide, overlap the ends by 2.5 inches. You can temporarily pin or finger press the overlap to hold it in place. Trim away the excess binding on both ends, leaving just the overlapped section.
Step 2: Align and Mark
Unfold the binding ends and lay them flat so they are perpendicular to each other, forming an 'L' shape. The ends should be right sides together.
As shown in quilting tutorials, you need to ensure your fabric is properly aligned. Lay one binding end horizontally and the other vertically, with right sides facing. Make sure the edges are flush.
Next, draw a diagonal line from the top corner of the horizontal strip to the bottom corner of the vertical strip. This is your sewing line. You can use a fabric marker or pencil and a ruler.
Step 3: Secure and Sew
Carefully realign the unfolded binding ends right sides together, matching the edges. Place a pin on either side of the line you just drew to secure the fabric layers and prevent shifting while sewing.
Sew precisely along the diagonal line you marked. Backstitch slightly at the beginning and end of the seam for added security.
Step 4: Trim and Press
Check that the seam is sewn correctly and the binding lies flat when folded. Then, trim the excess fabric, leaving a 1/4-inch seam allowance from the sewn line.
Press the seam open to reduce bulk.
Step 5: Complete the Binding
Refold the binding along the original fold line. The ends should now be perfectly joined. Lay the joined section flat against the quilt edge and stitch the remaining gap to finish attaching the binding.
Following these steps ensures a smooth, professional-looking join for your quilt binding.
