just get some clear (actually it's almost blue) water pipe from the hardware store - about 1 1/2" or so in diameter. Give hubby the job of slicing it up the middle on one side to open it out then into bobbin sized widths. It keeps him happy, he feels like he's helping out and no more messy bobbins ever! 1/2 yard of pipe cost about a dollar and will give you hundreds. I have used these for years and if I lose one, I don't have to bother hunting for it.
