I was looking about on the net the other day and found this gem. This is a really good demo for anyone who has never done this before. I always join the ends of my binding, instead of overlapping, or tucking one end into the other, so the join (seam) is not bulky. But it can be a bit tricky, opening the ends of binding and drawing 45 degree lines etc. And several times I have forgotten to add a seam allowance and trimmed the ends too short!
What is really clever about this video is that it only takes a couple of pins. No measuring, cutting (and maybe forgetting to add a seam allowance!) Just pinning, sewing and then checking seam before trimming. This is going to be my new method. Very interesting that it works using any angle too, not just 45 degrees.
