Unless, it’s hidden in plain sight and I’ve just somehow missed it, Hobby Horse offers more DIY show clothes than just pants and chaps. They have for a while now offered their chap and pant fabric on their website for those with sewing talent.
Today, though, I received the 2011 Hobby Horse catalogue and was excited to see they offer the “Janie Tunic Top” in all the same base colors as the chaps. It’s a plain tunic top made just for you to customize! I gave up long ago on sewing my own and have been searching for a plain pre-made top. Well, here it is. They cost $99.oo and so far, I’ve only seen them in the catalogue (request one here).
