Most of the time, all you need to do is make a good long length of tape and applying it from start to finish in one straight shot until it runs off the edge. However, sometimes you’ll either need or want to join two lengths of bias tape together in the middle of a run (eg, your bias tape goes in a circle).

As per usual, here’s what the brute force method tends to looks like. Simply folded over, it’s a bit chunky on the front, and really quite a mess on the back. We can do better. :)

Stitch things up to around the seam in question but leave a few inches of space on either side. For the sake of this example, pretend the left and right ends extend off into the distance along the rest of the garment. We want to make the two lengths of tape meet precisely in the middle to finish them off.

Fold back the ends, press.

Grab the two loose ends and align them on top of each other as shown. I’m leaving the folds in here so you can orient yourself to what’s going on, but in practice you’d want to mark this with a pencil or notch it with small triangles before pressing it flat. It’s a little easier to sew the following seam if you haven’t clipped it back to just the seam allowance yet.

Pin, stitch across.

Press flat and clip the excess until just the seam allowance remains.

You should be able to lay it nice and flat on your fabric now. Stitch across the last stretch.

Flip the tape around to cover the edge and finish your bias tape as per your preferred method.
