Some reap what they sow. Others sew what they rip.
My last experience sewing a button was a few years ago. I take some pride in the fact that buttons falling off my clothes are few and far between. Nonetheless, there it was, just hanging by a thread. Normally I'd go to the library and get a book on sewing; but our local library is currently closed due to renovations. So where is one to go for help? Youtube of course.
