I find this woman’s blog extremely helpful- an experienced seamstress writes about the basics of different kinds of stuff, she actually provides what any beginner longs for- making it all look really simple and fun.

She also shows how to work with leather and it doesn’t seem unreal anymore.

This website is similar, maybe little less helpful.

These, on the contrary are forums for those who have experience and are ready to share it: season.ru and osinka.ru
