has your mom SEEN etsy.com? show her all the stuff other people are selling on here, show her craftster.org, show her this board! make her see that other people out there are doing it FOR REAL and that you think she has the talent to join in. tell her to just give it one try, make a few things and list them, it's just ten cents to give it a go. point out that she's obviously got business skills since she's got 16 years experience, and she's got talent, whats she got to lose? go for it!!
i just started an etsy, and i like it, also, advertising is a main key. everywhere you can, post a link to your etsy, or tell people about it, make little business cards, anything you can think of to get your name out there. good luck!!!
Thanks.. thanks to everyone. I appreciate both negative and positive feedback.
