I'm a little crazy with the organization of my floss. I currently have 12 Artbin boxes organized by color group or something else like variegated, sparkly, etc. (They aren't all full so its not totally insane...right?) As soon as I get new floss I wind them on the plastic bobbins for storage. But when I'm making something where the length of the strands is particularly long I have been trying to use the plastic bobbins but they are kinda big. I can see doing this to make smaller bobbins for my working strands. Don't know why I didn't think of it. But that's the great thing about this site. Someone will come up with the idea you need. 😉 It's a really great idea for those who don't want to put out the money for the plastic ones too. Easy to write on the cardboard the color number.
I make my own bobbins also. I usually make them a bit indented for where the string wraps (basically the same shape as the plastic ones I have) but seeing this makes me think that it just isn't necessary. Thnx for this! 😎
