I found this cute pattern on Pinterest a while back. I made one in solid red, for a gift. Then I pulled out some cotton yarn that I've had languishing in my yarn tote and decided it was perfect to make one with.
And then I didn't use it, and so I made a white and blue one and gave them as a gift. Once you figure out the pattern, these whip up so quickly!
They look complicated, but truth be told they are quite easy.
Pattern here. I'll be adding this project to my Ravelry page soon, with some notes on changes I made to the pattern.
