I don't know if there are classes I went in blind!! I first bought a really cheap bear pattern and some cheap fake material to learn from (not the better mohair from my above bears) and learnt from there, I was soon drawing all my own patterns which are all above. My sewing skills and nose making are terrible though lol which is why I designed the more kawaii style button nose bears
I think there were some free basic patterns online too and advice for bear beginners

I am terrible I never take the easy option and take a class or buy a book I buy what I see and learn myself lol
