I've ordered a Vaja iVolution case but as it's going to take 45 days to deliver I decided to sew my own pouch. It's made from wool for the outside, silk for the inside, and a has a padded interlining. Enlisted the help of my mum for the final hand-sewn inner seam! It's snug fit but not a strain to put in. I'm going to add the drawstring cord but it's not really necessary. The wool is fairly coarse but I doubt fabric could scratch the plastic or chrome. Anyway let me know what you think!
