In some quilting communities, those little pieces of fabric you put under the needle to start your sewing are called, "Chain Leaders." They help you to start your seams and you will be surprised how much thread you save. After starting your seam with a chain leader, you will put one at the end of the seam. That is your new chain leader Cut off the first chain leader and then use it at the end of that seam. Keep rotating the chain leaders. Hope this helps and not confuses you. Good luck
