Finding discontinued yarn??

[jbsegal]

So, there's this crochet project I'm working on. I'm using Lion Brand Homespun in Montana Sky and Renaissance.

As I was unemployed when I started it, I only bought a few balls of each. I now need more but the bastages have discontinued Renaissance.

Does anyone have any idea where I can find yarn stores with stocks of out-of-production yarn?

(I'll be posting this to ljgenie, too.)

Thanks!
