Handwritten price signs say "car boot"; Canva says "give us an account and an hour". This says: type your items, pick a size, press print. Big type, readable from browsing distance, cutting guides included. Your sign list stays saved in your browser — no signup, nothing uploaded.
Print on plain paper and mount on card, or straight onto 160–200gsm card if your printer takes it. Dashed lines are cutting guides. For weatherproof outdoor signs, a plastic wallet over each sign is the stallholder's classic.
