I love a free, seamless pattern. This one was really easy, and I love the mistake rib border.
Pattern: Offset Wraplan
Yarn: Cascade 220 super wash, 2 balls
Mods: I only used three buttons instead of seven, not the best idea. I do recommend using more than three.
It did fit him really well before I blocked it. I wonder if washing might tighten it up a bit? At least he will be able to wear it for a while!
