Sorry - these go back to my pre-blogging days, no tutorial or pictures. But what I did, and I'm happy I did, I bought a pattern to make them. Doing the cuff turned out to be more complicated that I anticipated and without the pattern I'm quite sure I wouldn't have completed them. And that would have really upset me because I spent way too much on the fabric.
We've got 4 of these, green tops for the boys, red tops for the girls with a simple silver initial pin to tell them apart.
