Yeah, no problem with discussing it. You just have to be patient sometimes especially over the holidays.
I don't know how anyone makes money selling their knitting there. Or anywhere. Between the yarn and time involved to make a project worth selling the price would be pretty high wouldn't it? I'd ask those women at work what they'd be willing to pay for various things. Then figure out how many skeins of yarn you'd need and how long it would take you to complete it and calculate the price. See if its worth it.
Anyway, the site itself should have info on what Etsy's cut is so you can price your item accordingly.
