New quilting technique

In case you can't tell.....it's a pine tree. The technique is called paper piecing. The girl in our group that is expecting a baby had her Mom come in and teach us. It's a little challenging as your sewing by numbers backwards. I'm not happy with the colors but we were all told to bring a green, tan and brown. What we should have brought were five greens, two tans and a brown. So we all had to swap material around to come up the contracting colors. They don't blend very well but at least I got the technique down.
