I'll second the jist of Steve's post: pockets are most definitely a pain in the pleats to sew. It doesn't matter whether I'm making a kilt, a skirt, or a shirt, pockets are the part of the project I don't like. I recently completed my first kilt with pockets. It took quite a bit to do. Had that been my very first kilt, I really think I might have gone off kiltmaking forever somewhere in the middle of it.

I believe my point is that you should probably get a kilt or two under your belt before trying to make pockets in them. I wouldn't call my first pockets horrible, but I had advice from Steve and experience with the other facets of making a kilt to aid me.

Other than that, enjoy making your kilt and do let us see how it comes out.
