Some folks roll, some of us 'puddle'. You'll discover which you are more comfortable with. The thing to remember is to start with a simpler stitch (perhaps a diagonal - less bulk) and start in the middle, work to one side, then turn the top around and work from the middle out to the other side. Use a walking foot and as you go, you will feel more confident and comfortable. Then you can try FMQ and designs. You will make mistakes while learning - THAT'S OK! Chances are no one will even notice and they won't happen on your next top. KEEP IT FUN.
