I also stumbled across this website to make your own shrinky dinks out of recycled #6 plastic. Usually the clamshell containers found at grocery store salad bars and take-out container are #6. You simply cut out the plastic as shown here, then color with Sharpies and bake in the oven at 350 degrees for a few minutes, until the plastic begins to shrink and curl and then flatten again.
Knowing that in a few weeks, I had a Mother's Blessing to host, I incorporated the two crafts and adorned candles. First I wrapped the candles in raffia so the bead/ shrinky dink embellishment would have something to cling to since it kept slipping off the glass candle holder.
