This year I bought two canvases, some paint, and let my six- and three-year-olds express their creativity for their grannies. It cost us very little, but hopefully our mums will appreciate it.
I also whipped up a little boxy pouch from this tutorial for my partner's mother, and added a nice all-natural soap from the health food store. I will do the same for my mum, although I'm actually not seeing her tomorrow (sorry, Mum!)
I must say that tutorial is simple yet ingenious. A perfect use for small pieces of fabric, perfect for gifts, and even I, who am extremely zipper-challenged, managed it without issue.
