My daughter saw this https://www.etsy.com/uk/listing/777013958/crochet-hook-size-reminder-stitch?fbclid=IwAR0GEmPJ_2gKqOEJpXatSLbk_CFPfDbfoRfgH7SeFKhfFpm2PwVpQConjbM on etsy and asked if I could make something similar. You will need get hold of the keychain pieces to hang the markers on, or design your own setup. I printed them on maximum resolution, as they only take a few minutes each.
