And here it is!

Once I had all the pieces laid out and the tutorial ready on my iPad, making the pouch turned out to be a lot easier than I had thought it would be. I fiddled a bit with the end pieces on the zippers to make sure that all three zippers ended up the same length, but really, it is all down to taking care with pinning - honestly, you'd think I had no sewing experience sometimes!
Anyway, the pouch ended up quite nice, if I may say so myself. Since the main fabric is one with buttons, it will most likely be used for sewing notions, but I see it could also be useful for a lot of other things. So I need to shop for more zippers so I can stitch up a few more fore gifts.
