Inserting zips can be a bit scary but this tutorial will ensure that you get great results every-time.
Prior to starting the tutorial steps, it's important to ensure that your opening and zipper tape are well prepared:
- It's worth steam pressing your zipper tape before you start. This will ensure that your zip lies flat and there are no puckers or ripples. Moreover it acts as a pre-shrink, ensuring that the tape doesn't shrink in the wash and ruin all your hard work. If you're using a plastic zip, don't let the iron touch the teeth.
- It is worth considering if the seam allowances that you're attaching your zip to need to be interfaced. If you're using a lightweight fabric, stitching on the bias or curve, or if this is a side-zip fusible interfacing would help to stabilize the seam and support your zipper. You'll just need to cut two pieces of medium weight fusible interfacing, double the width of your seam allowances so that it crosses the seam line onto the main fabric; and an inch longer than your opening so that it extends below the bottom of the zipper. Fuse, following the manufacturer's instructions, on the wrong-side of your seam allowances.
