This is an idea I had last night and wanted to try. I hope you enjoy it because it's a technique that I want to play with a lot more. I like the rainbow coloring, but also look forward to seeing what other people will do with this simple, but intricate love coloring page.
So many adults who enjoy coloring, which is a good thing- this design will take some patience!
