I had an old frame lying around the house. It was missing glass and any hardware, and I’d painted it and put it in various places around my house. Suddenly, inspiration struck - an earring holder!
I used Size 7 needles, Crochet thread, and a 5-pattern-repeat of the Dainty Chevron pattern, found on KnittingFool.com.
I knit until it was about as long as the frame opening, then I bound off and attached the lace to the frame via staple gun. A helpful hint - staple gun the center of each side, then work around equally - that way you don’t end up with your lace cockeyed inside your frame.
You could use any lace pattern, and size frame, and any size yarn! Definitely do a gauge check so you don’t end up with a lace piece way too big or too small for your frame. (Too big wouldn’t be as bad as too small, though.)
