When my son was a little baby I wanted something like a mobile to hang over his cot. Inspired by a little book I have about creating spaces for children I decided on a set of flags. I made these out of felt which you can buy in pre-cut squares in a huge range of colours. The beauty of felt is that the color is double sided, has decent body to it and no hemming is required. I simply cut 10 triangles, sewed a loop across the top edge and threaded through some bias binding tape.
