I suggest you start with a nine block, and go square by square. The first quilt I did was a nine block. The #1 thing is to make sure you have 1/4" seam allowance. That is the key to every well made quilt.
Patience is the #2. Don't try to run through anything. Quilting should never be rushed.
I find it very relaxing now that I have learned the two lessons above.
Also, I recommend you take a beginners class at your LQS.
