This is a wonderful little "bowl". I made several. It is ideal to use up scraps from dressmaking. To put the slider back to the zipper can be a little tricky. But my sewing teacher showed me a trick and it actually works much better this way: on one side you cut off the coil - and only the coil - for about 2-3 cm. Slip the slider on the whole side first then on the cut side. You will have there a grip to grip the second side and can so easely pull the slider on the zipper.
