I hate to be the one to break it to you. But, if you've already removed the basting stitches (as you've mentioned) You're not going to be able to exchange it. There should be written notice of that on the invoice or an insert in there (can't remember which.) Most any kilt sales that sale of the peg have this "rule." You can always get the straps moved though... It's easier to make a big kilt small than a small kilt big. I have that econo sporran as well, I have absolutely no complaint with it. It has the "look" for not much cash. I wear it when I need something a little more "sharp" than my nylon nightstalker sporran.
