I love saddle pads. In fact, I believe you can never have too many. Why not have one for every occasion, depending on your mood and other factors? I have a hot pink all-purpose, bright blue all-purpose, white all-purpose, black all-purpose, tie-dye all-purpose, pink dressage, multiple white dressage, and an aqua dressage pad. They're relatively inexspensive and can be so much fun to outfit your horse in.

Here are some of my favorite ones that she's made:
