Their loss. Too bad, so sad for them, they lost a customer. Oh, well.
If you can just step by step follow the instructions for when to knit the stitches and not worry about the outcome it might make it easier. It did for me. I had a heck of a time with the cross stitches but after screwing them up repeatedly and refusing to give in completely and coming back to them, I finally got it and now I can do them. That pattern is easy for me, now. It would not have been when I was (and oh how easy to forget that pain till reminded) trying to assimilate them into my knitting.
