He also offers courses on Udemy. If you sign up for a Udemy account (free), you can see brief previews of his videos. That might help you decide if his teaching style works for you. :-)
I started by watching the free tutorials that Embird offers on their website. As Meganne praised the tutorials by Kathy Jones so much I bought a few of her lessons in the past, but did not find anything I had not already learned from the Embird ones. But if you want to follow a design from start to finish in one go, then Kathy's are nice. As are the free ones at Clipartopolis, among them two by Kathy.
Cathiejones meet Kathy Jones, Flying Needle Machine Embroidery.
There is no one better qualified, or whose comprehensive tutorials (to learn about digitising using Embird) are more reasonably priced, than Kathy's. Sadly she is closing her Yahoo group but she still has many of her wonderful tutorials available from her website.
