I learned to start in the middle and quilt out, but over the years, I've learned that if it's basted (pin basted, spray basted or hand basted) very well, it really doesn't matter. I try to do one block at a time, because that's what I can spread open under my machine. practice on a quilt "sandwich" for about 10 minutes before you get to your "good" pc, get all the kinks out. Write your name, do stars, squiggles, etc. At first, we all go slowly, but try to gain speed- it makes stitches less jerky and makes smoother circles/ curves. I say to go as fast as you can and still breathe! It's foot-hand coordination. pedal goes fast and hand speed matches. You can always rip it... Carol Taylor has a fantastic book with exercises to practice. Good luck! Welcome to quilting 301!
