My dad made up a whole bunch of the large thread holders simply by taking a small 4 inch aquare of wood and drilled a hole in the side & then took the old wire hangers & took part off & straigtened it out & put a curl on the top end & the other into the hole he drilled. He cut off a part of a dowel & drilled a bigger hole to put the dowel in the middle of the square. I took the cap from needles & cut the end off & stuck it in the curl & put my thread thru that. I also put an old spool inside the big one to hold it on the dowel so it didn't wiggle. It works great. Cheap too. Most people have a little chunk of wood around & an old wire hanger. He also sanded the block so it wasn't rough.
