This isn't a pissing match, it's a craft forum where people can show the things they made and give and receive tips from other crafters. I think you're being really rude to lidehtium and I can't see any good reason for it.
Also, repeatedly saying that someone is basically stealing someones idea and not giving them credit (which isn't the case here) is not the spirit of Craftster and trying to redirect people to *BUY* someone tutorial is really uncalled for and unnecessary.
Ding ding ding! Also, putting smiley faces into comments like that doesn't actually make them happy little comments. Also also, the first sweater coat I ever saw was NOT Katwise - so my personal inspiration to create a sweater coat does NOT come from her. Maybe she's who inspired my inspiration, or whatever, but I don't always know that. The OP said much the same.
And to the OP, I love this sweater. Really great colors, and I agree that the hood is just done PERFECTLY!
