I did pay to watch the first Quilting Quickly course. I loved it! She does cover a little what her You Tube tutorials did, but in more detail. I thought it was very worth my money! However, the new Quilting Quickly II course went up in price.
I really learned a lot from it and you can go back and watch it as many time as you need to. I agree it is mostly for beginning quilters....which I am!
I highly recommend it to all beginning quilters!!
Go for it!
