I use a candle warmer to keep my coffee warm; trust me, I need this when quilting and embroidery. I also use the binding things for paper, the ones with all those little "fingers" on them that goes thru the punched holes of the paper to make a notebook, to hold bobbins with thread on them. I can group them together by thread type, cotton, rayon, etc and they take little room and hold the lose ends from going all over the place and its easy to see what color you have. You can even cut them down to size so if you are carrying things to class, etc it'll fit what ever size you case is. You can get them at any office supply store, I use the med size ones for the bobbins.
