I am self-taught, so take heart...it is possible!!!!
There are some AWESOME videos on youtube and I really think that's the best way to learn. It's really difficult to stare at pictures and try to figure it out. It's so much easier to see it done by a real person.
I have some patterns for sale in my etsy shop (mostly for children's hats) that are written especially for beginners. I really try to write in a way that's easy for anyone to understand.
The other great thing about the patterns you buy on etsy is that most sellers also offer email support if you get stuck or have a question. So if you're having trouble understanding terms in the pattern you can contact the author directly, which is wonderful
