I like her approach. It makes it all doable. Is not tedious and allows you to see progress immediately. My sewing room has lost much of the "clutter" but is still over full. Need to use more fabric and deal with an ever growing bin of scraps and less than FQ pieces of fabric.
One thing I did but wasn't from "Just Set It Done", was last summer I hung all of my finished tops with their back and or binding on clip hangers. It saves on re-pressing a folded quilt and I can just "grab and go" to finish a UFO. I can see the shift in the number of finishes which makes me feel accomplished. Now it is habit to press and hang what I can't finish immediately. Just another idea that works for me and might work for you.
