I am new to quilting and know I have ask many of these questions. What seems easy or obvious to experienced quilters is not obvious to newbies and if you have never sewed or used a sewing machine and decided to take it up like I did after I retired the language is different than what you are use to and you are so intent on doing it right that you ask about everything. The talented people on this forum have such a wealth of information and are always so kind to share. You will never know how many times you have helped people through a mess or helped to get them started. You have me. Thanks so much.
