I found this really cute Tree Garland to crochet. I found the pictures at Meli Melum! Then I found a really great tutorial at The Royal Sisters. Each step has some great pictures. The steps are easy to follow.
I think this is a great project to do with your left over yarn bits. It would looks so cute on a fireplace if I had one. I have a niece who just started to crochet and I bet she would love this pattern.
When going to The Royal Sisters you will find patterns for including a heart and a star.
