SIZE depends on your crochet density and yarn used as well as the hook size.
If you use the same materials and tools as I did, you`ll get booties suitable for a 0-3 months old baby. Materials used: -Plush Yarn 131yards (120metres)/100gr (Himalaya Dolphin Baby color 325) -5mm crochet hook -2cm ribbon for decoration -transparent glue (for fastenning the bow) -transparent nail polish -scissors -plastic needle for plush yarn -sewing thread and a tiny sewing needle (for sewing the bow)
