Part one:
We buy, make, or find wooden shapes at home. Some awful colorful decorations that you would like to throw away but are at the bottom of the wardrobe are also good. In fact, even wooden ones do not have to be.
At the beginning, no matter what it is, I cover it with white paint. Sometimes I put darker paint underneath (brown, gray), but why - more on that later.
Children will be perfect for this role. You can't spoil anything here :)
Part two:
We paint the hearts white, of course. Mine already had burned edges, but if they weren't, I would have painted them dark first.
You need to put at least two coats of paint. Once they are painted to get the "antiquity" effect, I scratch the sides with a pair of scissors / knife to dig into the darker layer. It is better immediately :) And in fact, some of them can be left, tied with a ribbon or thread.
However, if we want to impose an inscription or a picture, we must do this:
1. We print the pattern in a mirror image. Of course, I forgot, what you can see in the photo below. Fortunately, I quickly realized it :) We have to print it on plain paper, on a laser printer. It can also be a photocopy. There cannot be photo paper or an inkjet printer.
We apply a second or another layer of white paint and the cut pattern is "glued" (simply applied and pressed) to the still wet paint.
We leave it to dry. At least 15 minutes. We can speed up with a dryer or other invention. When it is super dry, dip your finger in water and rub the "stuck" paper. The paper starts to "roll" under the influence of water.
