My horse Auda is half Belgian half QH so she has a really wide back. I've tried a couple different wide and extra wide saddles, English and Western, but they were all too small. Yesterday, I got her a western draft saddle which is a really close fit but is just a little too big. I'm thinking I need to get her a build-up pad or and under pad or something to fill that extra space. I have no idea where to look, though, or even what they're really called or what to look for in a good one.
I was thinking something like this: http://www.thinlineinc.com/store/car...ct_detail&p=30
Except I don't have $153 to spend and I don't use sheepskin or other animal products.
