I've seen quite a few vintage lace collars floating around Etsy. I think that they are lovely (see this, this, and this). I don't typically decorate my home with crocheted doilies and lace, but I love the idea of decorating oneself with it.
I've had an old ecru doily in my stash of things to be repurposed, and I finally got around to transforming it into something new. . . a lovely little collar. Want to make one yourself? Here's how...
Start with an unwanted doily, mine was about 10 inches in diameter.
Cut up one side of the doily to the center. I ended up rounding off these two sides, because I thought that it looked better with the scalloped edges.
Cut a hole that is large enough for your neck. You are most likely going to be wearing it at the base of your neck, so measure at the widest point. Once you've cut an initial round, you can adjust it as needed.
Finish off your raw edges. Initially I had thought to use a thin double fold bias tape for this step, but then my sewing machine quit on me, and I was then forced to use the rolled hem function on my overcast serger. It worked quite nicely, I only wish that my thread was a better match.
If you wanted you could hand stitch the rolled hem so that it is turned to the underside of the collar. You could also sew a thin velvet ribbon along the rolled hem to make it a bit more polished (I'm going to have to wait for my replacement machine to show up before I tackle that).
To finish it up I attached a "pearl" from a broken bracelet. The collar is fastened by slipping the pearl through one of the holes in the lace.
That's it. A super simple and easy way to turn a household doily into a lace collar.
