This is a really easy and fun project, great to do while watching TV (I would recommend DVDs of That Girl). I started out with felt that I picked up at the fabric store, wool felt would be nice, but I just used good old acrylic and it was fine.
I made a pattern to trace for the leaves, I made Birch, Oak and Maple leaves. I just went to Google images and looked up leaf line drawings to get the idea of what they should look like.
After I cut out my leaves I embellished a few of them. And I couldn't resist adding a few buttons of course!
