I love those zippered blanket bags! I spent last weekend reorganizing my yarn after reading a tip from someone here in the forum about using gallon ziplock bags for storage. Now I only have one plastic tote that is full, one queen-sized zippered bag that is full of all my cotton yarns, and two big recyclable shopping bags from Michaels full of various Caron Simply Soft yarns that I went crazy over and bought a bunch on sale (and then bought more every time I went into Michaels or JoAnns) that I stored in the ziplock bags. They work great. I squeeze the air out as I seal them and make even more room.
Still, I keep telling myself, "I will not get any more yarn until I use up what I've already got!" (sound familiar?)
PJ, you're right about moving revealing the truth about your yarn stash! We moved my mother (and her gigantic stash) twice over the course of about 3 years. Since my dad passed away, she now has an entire room full of yarn (kept in the plastic stacking drawers)and quilting fabric (kept in smaller bins in the closet). Every time my brother goes in there he tells me, "That's your inheritence!" (Hey, I think that's great--just as long as I don't "inherit" it any time soon!)
