Additional notes:
* I used: 3,5mm crochet hook, a variety of tapestry needles, scizzors, dark brown sewing thread, 16cm brown zipper, and mostly size 2 acrylic yarns (mine were leftovers, so unfortunately I can't tell the specifics better than that)
* after finishing each side I slip-stitched around the edges, using the same dark brown yarn as in the rest of the pattern, and then used mattress stitch to connect them, leaving only a hole at both sides of row 25
* for security I lined the inside with extra fabric
* I sewed a 16cm zipper inside to finally cover the hole (could be a little shorter one tho)
