Reading through the "Help DD needs a new glove" posts, I've been surprised by references to gloves made for baseball popping up. Most of those I've seen are at least 12"+ gloves. At what point is a baseball glove a good softball glove? My daughter mainly uses a catcher's mitt, so that's easy, but I've seen baseball gloves being suggested for both fielders gloves and 1st base mitts. Is there no difference between a baseball and a softball glove once you get to a certain size?
