Lori,
If you used the Quilts for Kids kit, life is easy. Start in middle, use the corners of the square blocks to keep your lines semi-straight. Since they want the borders quilted more heavily I did parallel lines of decorative stitches (If your machine has any) about the width of pressure foot apart on all the borders. You could also 'echo quilt' around each square patch. I make placemats for Meals on Wheels also and do my trial designs and practice on them. Then the placemats go to the local Meals on Wheels to be distributed with the Easter meals.
By the way, I do not see the need for a walking foot for these small quilts with fairly thin batting. Just set you machine for medium weight fabric, about a #3 stitch length, and slow down. Have fun.
