If you are good at drawing or painting, choose something that involves decorating, like making cards or charcoal drawings. If you find that working in three dimensions and modelling things in your hands is what makes you tick, then go for clay, candle, or soap projects.
Finally, if you are patient and find repetition soothing and relaxing, there is nothing better than crochet or needlework. Some projects may take hours, others weeks, but all of them can be done for pennies if you engage your creativity.
