Okay so last yearin school I made a lycra hood for my gelding (a little tight so for my other gelding)and I was looking around for shoulder gaurds and they are expensive!! And I don't want to spend 100 bucks for three if they are going to ruin them. When I could make them for less. I was wondering what I would have to measure to make them the right sizes. My gramdma is an amazing sewer..
