I know someone who sells the glitter glasses and she sells loads!
She crafts other, beautiful, stuff, but she says people just won't pay for a crocheted blanket or a patchwork quilt. So, she makes tat, sells it at a profit and uses the money to fund her crafting!
She had something ridiculous like 40 odd glitter glass orders for Christmas. Yet the only person who enquirered about the blankets she makes called her a money grabbing con artist when she quoted him!
