If you haven't been tempted to dip into Craftsy yet (which I thoroughly recommend that you do) then there are a few free taster classes to wet your appetite.
The first is a Sewing Machine 911 - which as it says on the tin is about maintaining your machine
The second for quilters is the Craftsy's Block of the Month.
I have signed up to both of Gertie's courses (more for techniques to apply to projects that I want to make and to the Susan Khalje class, the Couture Dress.
Have you tried any of their classes? What do you think of them?
If you are after some other free tutorials, then there are some great sewalongs for different clothes patterns on the web. Also check out Tilly's tutorial for her button down picnic blanket skirt that she made in gingham.
