I haven't knit any of the Felted Clogs, but I would recommend reading her COPYRIGHT wording and follow the guidelines. It gets really dicey when you knit a protected pattern and then try to sell it in a public arena, such as Ebay, Etsy or your own Blogspot. Designers know how to throw out an 'internet fishing net' that will bring in ALL POSTS and SITES that are featuring their designs. There is a name for that 'fishing net' but I can't recall it now. If you are selling a protected pattern anywhere on the internet, she will find it if she's looking! And since this is how she makes her living, she probably will be looking.
It is impossible to make a living off 'knitting' by itself. No one ever wants to pay the price of a handknitted item, even if you charge just 50 cents per hour for your labor!
The only way to really make a living at your knitting it to create pattern designs and sell them. And hope that people buy them for their own use only.
You are right to ask about this subject! Thanks for checking!
