I bought bandannas ages ago for this project and finally got around to it.
Can't believe it took me so long because it really is as easy as she says it is!
I do have a few recommendations though: I added a little stitch over the ribbon right in the middle as to prevent my daughter from continually pulling the ribbon out of the pocket.
I also used a thinner ribbon (she used 1 1/2in my is 5/8 and 7/8), I found it much easier to keep tied.
Same pattern + $2.50 towels from Target + a little more ribbon=
too bad we were both too sick to make it to church for her to show it off:(
