I inherited from my mother-in-law a set of bags on rings -- I don't know th e brand name, but they were zip top with two holes on the edge -- they were bigger and thicker than the bags I've found more recently. She picked the bags up YEARS ago and had a large set of DMC in them -- already numbered.
After giving them to my wife & me, she got back into needlework and ended u p making a whole set of bobbins in boxes. I don't like the bobbins. Seems l ike the floss ends up getting fuzzy. Could that have had something to do wi th the winding?
If I could find the big, thick bags again, I'd buy up a bunch! I love it as an organization system -- I group the bags by number (any other scheme wou ld NEVER work for me). I pull out the bags needed for a project and keep th em on a ring in my bag. I can even break it down further if I want to trave l and only work on certain sections. I love it!
