I understand what you're saying. Over hear in the Phoenix area it gets too hot in the summer for most of the kilt jackets, or really any kind of jacket. On the other hand, it almost helps to have something with sleeves just to keep the direct sun off.

You know... The back of the jacket I'm working on could be held in it's shape, for the most part, with a belt.

It basically just has a fold down each side, and is sewn down in the waist area. if there were a belt and some kind of keeper loops at those points, it would probably work.

It reminds me of a bird's tail.

Anyway, I started sewing on the hems of the waistcoat this evening. The jacket is mostly finnished, but I need to go over it and look for any thread tails etc. I'll keep working on it.
