So as usual - I painted the fabric with my Sun Dye Fabric paints (although any fabric paint will do sun prints.
Then I just laid out the shapes all over the fabric
Then I just left them to dry. It wasn't a particularly sunny day but these paints work so well that within half an hour the fabric was dry and the images imprinted.
It was fun gathering up all the shapes
These are some of the resulting fabrics and they are now all available on my website in case you like them but don't feel like making your own.
