I just deal with the mess when washing fabric before using, as some have said.
HOWEVER..
I washed two quilt TOPS this weekend..they had been finished for months and hanging on a quilt rack , 1 1/2 " log cabins. Dusty and odorous I felt....well don't anyone do this....the border didn't fray,it was on straight of grain...but the entire inside, all the little strips, a complete jumble of tangled threads, and some split seams. The effort to repair was overwhelming so I threw them out. Lesson learned the hard way. Each measured 80 x 90 and I did enjoy making them, so no sorrow. P.s. They were scrappy.
