When I first started cross stitch I hated how many tools I had lying around the place. To combat this problem I decided to make a hidden book safe come hussif (sewing kit). Instead of cutting the pages, which might cause problems due to the sharp needles and scissors, I layered foam sheets.
This worked really well, and until I started updating my sewing kit, worked very well. I had intended to create this as a bit of a proof of concept, with the next one being larger, however since then my kit has exploded in size and I never got around to creating it.
