|I think the tip for making binding using a couple of needles in the ironing board the width of the toe of the iron apart has been posted before. I couldn't find it today, see my photo if its new to you. Whilst making some for bound seam allowances to neaten the inside of a garment, it occurred to me that having two more needles a bit further down the ironing board (about six inches away from the first set), arranged so that the space between them was half the width of the space between the first set, would allow me to have the binding pre-folded and ready to slot the raw edge of the seam allowance in. So, with the first step, you start a bit off the hard way, folding and pressing, then thread it under the needles so that the binding folds itself edges to middle as you pull through. Then, when you have six or seven inches or so beyond the first two needles, fold a bit along the centre line and press it. Thread this bit under another two needles. You can tug it through, pressing the first two folds between the first set of needles, and the final fold between the last two needles.
Works fine, ends up like commercial binding but matching your lining.
