After writing my post last night, I sorted out the bits dyed by independent dyers and e-mailed a friend who expressed interest last year in those types of scraps. Then I posted on one of my online boards and offered the remainder to anyone who might be interested, for the cost of shipping.
Who knew there would be so many people interested? I just packaged up 18 mini and full-size skeins, weighing in at about 2 lbs. I put some more scraps into a bag for the kiddo's preschool. I stuffed the things that I absolutely could not part with (1.5 toddler socks, a barely-started felted bag project, some scraps for a baby hat for the friend who dyed the yarn) into an old diaper bag. Now I have a tote for all the new undyed yarn. Yay!
