Though i would go into more detail today!
When you sew your strip on the front be sure and pull it away from the battening and backing, then make sure as you sew it down slowly.
Sew it to the front 1/4 inch , no bigger
On the back strip just fold it under enough so that when you sew it down it catches the edge. I usually turn it over and sew down the front strip . I started with that big stack of singles and just sewed one every once in a while as i read blogs on the 'Grow Your Blog' site
I finally just quit because Monday is treadmill night and i needed to clean up the kitchen before i got on the treadmill.
Hope every one up north stays safe and warm.
Have a great day!
