I have signed up to do a free motion machine embroidery course at Craftsy.
I’m only up to Lesson Four (of eight), but I am very impressed. You can watch the videos whenever you want and then complete the home work in your own time.
I’ve already picked up some useful tips: You can just use over-locker thread as bobbin thread (must be cheaper than the special bobbin fill) and you can use non-woven interfacing as a stabiliser.
I haven’t got any pictures to show yet because my free-motion leaves a bit to be desired, but I’m definitely improving and I have learnt it is better to go slowly rather than super fast!
