Used cereal box
Draw out your crescent moon on the back of the cereal box. Then draw another crescent moon inside the first moon. You'll need each moon to be about an inch apart all the way around.
Put a dab of glue on the back of one of the ends and hold it down on it until it sticks.
Start wrapping the ribbon around the moon shape, going from one end to the next. It's okay if you need to cut your ribbon on one of the ends and start rewrapping the second side. We also added more glue as we went, so the ribbon wasn't only being glued on the ends.
When you get to the end, put a dap of glue down to close off the wrapping. Cut off the excess ribbon.
Here is the detail of our moon.
Oh, and for those that are curious, yes, I have a chalkboard wall in my studio for my to do, to buy, and to make lists. My daughters, however, like to come in and draw all over the bottom half. This week it was a mural of a friendly dragon blowing water on a village to cool it down during a heat wave. I think they are getting their imagination from a hot, summer Ramadan :)
