Pretty Colors. There are many tutorials on the web for these. I used a Dutch one but you'll find an English one in the link on this page.
I used different colors Phildar Coton 3 and Schachenmayr Catania.
I plan to make a whole lot of them and hang them together with crochet flowers on a long ribbon.
