Wait until it's completely dried, then cut out geometrical shapes: 2 sizes of circle, diamonds etc, either by :
- Using a special scrapbooking craft knife while leaning on a piece of thick cardboard and cutting all the way round the outside of round objects (small lids etc...). Note that you have to press down hard to cut both this repositionable paint (which is obviously quite thick) and the plastic sleeve at the same time.
- Or with a pair of fine-tipped scissors
place the shapes all over the container, the painted side against the glass, then peel off the piece of plastic sleeve.
