The doily is lasered into a flat design that loops and weaves into itself to make a raised edge around the frame. Most of the designs incorporate two layers of felt to make two-colored lace. Designed in Inkscape and lasered at full speed at 10% power.
With a light touch, you can get very fine filigree out of the felt that holds up surprisingly well, even after being run through the wash, which has happened plenty of times to the ones I made for personal wear. These seven are available on Kickstarter right now through Laser Lace Letters.
