As it came I inspected the holes, not that big but many, right in the middle of the veil. I promptly put it in an embroidery hoop to keep the sheer fabric straight and still, and then I drew threads from the leftover fabric intending to use them to make a darning.
It turned out to be nearly impossible to make it as neat as I wanted too, as the weave is so very thin. I had to turn over two threads a stitch instead of one and it easily turned into wibbly-wobbly lines.
As I darned the holes the darning made tiny crosses on the veil, not entirely undecorative in my meaning but I sure wish they would come out more even than they did here. It got better after a good pressing with a damp cloth between the fabric and the hot iron. All in all, the veil is now mended and can be used as a more everyday veil. And the new one I made for my friend can be for Sunday finery.
Tomorrow they will be sent back by post to their rightful owner. I hope she will find the darned veil usable again.
