Wouldn't it be just as easy to make my own, I thought? So I bought fabric, ribbon for edging, and when my mother came to visit, she brought her sewing machine. We based the pattern off the one at the barn I liked most - I don't know what brand or even what size it was.
It was a bit of a rough first attempt, but the cat thought it was the best day ever.
We sewed a 1.5" ribbon doubled over around the edge, which I would probably not do again. I think I'm going to want a blaze orange one for hunting season (coming up soon), and I'm already thinking about new edging material.
Here's the finished product. I LOVE IT, and have gotten a ton of compliments every time I ride in it. I think it looks so much better than any of the ones you can buy. It ended up being less expensive in terms of materials (which I picked carefully to be on sale), though perhaps not when you factor in the labor cost of figuring out how to do it and then the sewing itself.
Have you ever made something from scratch for your horse?
