Agree. I just change threads within the section of the quilt being worked upon, unless one particular thread will be used heavily throughout the quilt. Then I will use that one first, all over, since it will uniformly stabilize the quilt sandwich for me. Then I'll go back and use the other threads, one area at a time. HTH
