Yarn with a memory

Isn't it funny how sometimes when you're putting together a box for one swap, that it makes you think of another one you should do? That's what happened to me...I thought, wouldn't it be fun to do a swap where you only send yarn colors/balls/partial skeins that have a memory attached...hopefully good ones, but there could be some catharsis here too...and enclose, with the yarn, a note that explains the details. I know that two of my additions will be, a ball from the first skein I ever knit anything from (oh, yes, it's acrylic! lol) and a suri merino ball from a pair of baby booties I knit for my friend's first child. I just like the idea of sending warm fuzzies of both types--yarn and thoughts--or of helping someone find a place for some yarn that they don't want to see anymore, but needed it to go somewhere to someone who understood there were memories associated (boy is that a horrible grammar passage). Let's say international is okay (since they should be pretty lightweight), I'd hate to turn someone away who needed it. Send whatever you want, but please make it at least 2 skeins worth total, so that your recipient can do something. No no-sends, newbies with profile and a message. Anything else, or other suggestions? I'll give a fairly decent time length so people can really think about what they wish to send.
