Base after R6 = 2.5” across
Cup holder depth = 4.75

Needed to add an extra round for a deeper cup holder, so R11 was another granny round and R12 was my sc round.

Need photos of Brooklyn’s blue cozy which I started on the plane to Indianapolis.

I wish I’d had the other pattern for a chair cozy (project here) before finishing these. That designer uses snaps to attach the bottom of the two sides over the arm of the chair. I think that’s going to work better than these ties, although the ties are definitely easy enough.
