How difficult would it be to add slanted side pockets, like on jeans or trousers, except with zipper closures, to an already made wool kilt? It seems to me it should be fairly easy to put a top and bottom lock stitch between two pleats on the sides, where the pockets are going. Then rip the seam between the lock stitches and add a pocket. A zipper closure would probably also be necessary. I've only been wearing kilts about six months, and have several utility kilts, but do not yet own any tartan or wool kilts yet. My concern is, being a farmer, wearing a sporran all the time would not be possible.
