Way back in the day, people used to make a living selling arts and crafts and useful objects they handcrafted. They'd create their products and then meet in the local town square or village market to sell them.
I'd arranged them and rearranged them on the floor at home until I liked what I saw. I didn't want all the baby photos in one spot, or too many posed photos in a row. I was going for random -- a fireworks display of fun.
Thefts are an occasional, sometimes regular, nuisance for artists and craftspeople who sell their work at fairs and festivals, despite the sincere efforts of the event sponsors and the artists themselves to stop them.
