I've been trail riding with friends who ride western, but I use a dressage saddle. I don't have any dee rings on the back.
Rather than buy saddle bags, I'm hoping to be able to make some custom to all the things I'll be carrying, but I can't find any general patterns online. Following (and editing) a pattern is a lot easier than making one from scratch.
Know of any good ones for cantle or pommel bags? I've got dee's on the front, so those can clip or tie on there, but back ones need to have velcro loops or something for the girth billets.
