Don't be discouraged, just pick any of the simple block patterns mentioned here and begin. Sounds like you have overwhelmed your mind with to many designs.
If you have questions or concerns ask and you shall receive many answers. What you really need is a quilting buddy, less intimidating than the whole crowd. Although there is never a question that can't be answered. Someone always has the answer.
I am really busy at the moment with a quilt and lots of deployments for the Marines but I would be happy to help you with decisions and getting started. You may have to wait a few hours for me to get back online but I always answer, it just takes me 3 to 5 hours for each deployment.
Hugs,
Sharon
