I'm not good at keeping my fabric tidy & neat, so do try to control my threads. I typically vacuum at the end of a project right before I have to try to iron my pieced top before I quilt it. I hate having to pick all the threads off the quilt top again. I keep my tops thread free as I go. I really detest all those little smidgeons of thread staring up at me from the seams. I don't get the thread build up in my rollers of my chair, because most of it goes in the trash can which sits beside me. I have 5 trash cans in a two room area. There is always one near me, whether I am cutting or sewing.
Just an FYI...about the threads for the nests. Years ago, we raised parrots and had read that the thread was a good idea. One of our African Grey babies got a thread around a toe and had we not seen it and cut it off, would have lost the toe. I don't know if the same thing could happen to much smaller outside birds, but thought I would share our experience.
