I do believe I read the advise of " 15 minutes of sewing" here but..... {& I apologize I don't remember who posted it}
I took that adivise last week and it worked for me. I think we get this mental thing going of the task as hand & end up telling ourselves we don't have enough time right now but telling yourself you will sew for just 15 minutes,,,,,it really does work...TRY IT..and again thank-you to the orginal poster.
