Owl, if you want to sell cakes, this is a really good time of year to try it. People want small gifts, something nice to bring to a pre-holiday lunch, or stuff for 'bring a plate' parties. Biscuits are good too. The person who has a stall next to my plant stall at the Farmers Market, selling fancy biscuits, reckons she makes plenty of money in the few weeks before Christmas.
Are you anywhere near the Salamanca Market? Or does your town have a market?
That said, it's hard work! As in my day today 1. Load plants and flowers into car. 2. go to Farmers Market, unload plants and flowers. Mind the stall for four hours, early morning. 3. Load remaining unsold stuff into car. Drive home. Unload heat damaged plants and put in shade. 4. Repack car with fresh plants. Drive to other end of town. Unload car and set up for street market accompanying town Christmas parade. Work the stall for 5 hours. Clean up and pack leftover plants in the dark. Drive home. Unload. Mercifully that isn't every week!
