I know why I was having problems with my Hermione hat that I made a couple of months ago. It's a bit embarrassing to admit, but I've been knitting wrong
. I think I had knitting dyslexia and was doing things backwards (I had my right needle going into the loop on the left one wrong).
I don't know what finally made me realise that something didn't look right when I knit, I think I was looking in a book for something and thought to myself, that doesn't look like the way I'm doing it. So, then I came on here and watched Amy's videos and had to re-teach myself all over again, but it was well worth the effort because I'm making the hat again and finally have the zig zag in my pattern looking the way it's suppose too!
I have to finish another project my old way because I have way too much done to frog the whole thing, but I'm glad I finally figured things out for future project. :D
