There is something satisfying about quilting as you go. It is quite gratifying - you get the beautiful straight line quilting without having to wrestle your quilt through the sewing machine.
To be fair, my experience with this type of thing is somewhat limited. I like to make quilts with all sorts of designs, not just log cabins, but after making these blocks for the do.good stitches bee I almost couldn't stop. If only I didn't have school I would've made them all day long!
This is like instant gratification. Or at least almost instant.
