If you don't try, you'll never find out how you'd do with them. You may discover that you are the BEST at whatever, triangles, circles, paper piecing...but you won't know if you never try! :)
I may not excel at everything I try, but I'm not afraid to give it a go! My first attempt at FMQ on a real quilt was supposed to be clam shells. They looked more like a turkey on wheels. LOL I kept trying and now I'm so much more confident. I've practiced feathers, but haven't done them on a quilt yet...but I'm getting closer to that day with each project!
Don't take your attempts so seriously...laugh at yourself when you screw up! Relax, try new things and have fun!!!!!!!
