Pin It MADE blog. Now, just so you know, I didn't plan using the exact same towel as she did, but it was the only towel that matched my swimming suit at Target.
It was super simple - the only pain was having to hand wind the elastic thread on the bobbin for the shirring. I would definitely suggest making one though. It's great because your towel stays on you without you having to wrap it or hold it in place - which is great when you have kids to take care of :) Check out her instructions and if you have any questions let me know!
