This pattern is something I have been working on for a while, I got the idea while I was looking around at some cup cozies and some failed knit stitch hats I have tried in the past. This one uses a pretty simple repeat for the hearts and is nice and quick to work up.

I measured my own head as I went along, but if you know the measurement for the finished hat, just keep doing the brim until it is long enough.

Can be easily adjusted for larger or smaller dolls, just increase/decrease hook size/ or use different yarn weights.

Pattern is easily adjustable to accommodate smaller and larges sizes
