Altogether I made 6 of these, including the first test blanket and then five of them to send for a Stablemate prop swap.
Here are all five being tested out on a small herd of small horses.
They feature working buckles all around. These are the tiny hardware pieces that I've been fabricating lately. I figured out how to make them pretty easily and I might turn that into a tutorial at some point if anyone is interested.
The blankets are on their way to their new owner and I hope she likes them!
