I find the problem and correct it. A few time doing this and I know what to watch for and prevent. It may take longer but once done, my quilt top goes together perfectly. Having every seam match and laying flat is a good feeling of accomplishment for me.
I found a nifty little thread helper. A command strip on the machine bed will hold the thread tails out of the way when you start to sew.
