They are so easy to make. The first thing you need to do is paint two coffee filters. We happened to have a red bingo marker. It was great for coloring the filter red. A few little bingo marker dots paint can go a long way. The filter absorbs the paint and spreads.
Then the coffee filter was opened up into a half. JDaniel used the hole punch to create two holes near the fold. His holes ended up a little off center, but that was okay. I would have put them closer together, but I was not in charge of the hole punch.
