If you love flowers or even a sort of retro look for a home this is a really fun project for your window.
Another idea would be to crochet these flowers to decorate a little girl's bedroom
The pattern is called a Half Flower and is created by Robin on the Once Upon a Pink Moon Blog
The tutorial for the pattern includes step by step photos and complete instructions.
I have not attempted to make this pattern yet but it seems fairly easy to crochet.
