Giddyup! Pony Hood
If you’re not picky about formatting or printing, this pattern is available free on naughtyneedlesknitting.com
Here’s a charming pattern that got cut for space. It’s a fitted hood with a collar strap, and aside from pony play, the basic hat pattern can be decorated to produce any number of animal or novelty effects. This is worked with 2 strands of worsted, but you can sub one strand of bulky, worked to gauge. You can easily adjust for size buy varying the thickness of the yarn.
The bridle and bit are removable, so you can hit the slopes in your pony “hat” without scaring the tourists (or go ahead and leave the bit in place, if that’s your thing).
