I just searched the forum and I couldn't find anything either. I'd certainly like some front pockets on my X-Kilt, but my understanding is that they are hell to make.

For the rear pocket, are you wanting the pocket inside or outside the kilt? Because one on the outside (like jeans) would fairly be easy, but an internal rear pocket would look better and shares the extra complexity of a slash pocket.

I'm no expert on sewing, but what I can tell you is that for front slash pockets, you need to make the hole, reinforce it so that it doesn't grow, and attach the material that holds everything. You may want to examine some pants pockets for an idea of how it should be constructed. Based on a closer examination of my pants, it seems like the basic structure should be a hole hidden behind the pleat, with the thin pocket material sandwiched in by a strip or 2 of the kilt material to reinforce the hole and hold the pocket material in place.

Beyond that, you also have to consider how it will all hang. I don't think I can help you much here.

Since I am making my own X-Kilt this week, and will be practicing my sewing with some extra material, I may try to make some pockets, and figure something out. If I get comfortable with it, I will probably add some to my kilt. If between now and then someone does post detailed instructions, that would be cool, but even on my own I bet I can make something that works. The upside of a kilt is that you can hide an ugly but functional pocket between the pleats.
