Place lace in a small bowl and cover in fabric stiffener; soak for 15 minutes.
Remove lace from the bowl, allowing the excess to gently drip back in to the bowl.
Wrap the wet lace around the rim of the other 2 small bowls, allowing it to hang. Use a spot of tacky glue to hold the overlapping ends.
Put the bowls in the microwave, one at a time and microwave on high power for 30 seconds. You may hear some crackling in the initial phases. Just watch the microwave all the time. Continue to microwave in 30 second increments, until the lace is dry to the touch. You may turn the bowl bottoms up past this step.
Once dry, completely spray the crown with more stiffener and return to microwave. Microwave in increments of 15 to 30 seconds until completely dry. I also wanted to fold the edges a bit and I did this after the first spraying session. I just lightly sprayed on the first session, folded the edges and microwaved.
Repeat the spraying/microwaving stuff until you're happy with the level of stiffness. I did 8 steps.
Remove crowns from bowls, put rubber gloves on and spray paint in color of choice, on both sides. If some of the stiffener has closed up some of the holes in the lace, clean it out with the end of a pin. Apply several coats of paint; the crowns will stiffen even more.
On the last coat, do a clear paint coat then immediately apply glitter of choice.
Wait for the paint to completely dry before moving to the next step. Do not dry in the microwave!!
When crowns are dry, attach some glitz with a hot glue gun.
I used crocheted lace as it gives the sturdiest results and I was also more confident to use it in the microwave.
