What a great list on hints!!
I use an empty wine case which has 12 sections for 12 bottles to hold all my different stabilizers, slides out of site under my cutting table nicely.
I use a foot sanding thingy at the dollar store for removing stray threads after removing stitches, just use the edge and run it along the line of stitiches. Ive heard of people using nail files in the same mannor.
