This is the pattern I used for the class I taught at Lovelyarns in Baltimore between 2006 and 2008. It’s very simple, but a little oddly written because I wrote it to explain clearly.  Four sizes!  Toddler, and women’s small, medium, and large.  Gauge does count because the yarn is so stretchy.  Size down if you’re in doubt.

This pattern is now also available in Polish!
