I have a new horse (a little QH mare) and I'm not sure if she needs a medium tree, a wide tree, or something inbetween. Is there a way I can tell without having the saddle in person to try on her? Also, I hear about "tracings"... I'm not sure what that is, but it sounds helpful.
I grew up in a world where "medium fits all", so I should know things like this, I don't
Sorry if this has been asked a lot- I've been gone for a while.
