Hi I noticed on YouTube yesterday Patsy Thompson has added heaps of video's. There's a Beginner Machine Quilting series and an Intermediate one too. Here's one of the Intermediate ones if you want to have a nosy. They are all really good and she shares a lot of information on needles, thread etc too.
In the beginner series there's a very interesting 'Spray Basting' lesson. Pasty spray bastes on her wall! To watch her other lessons, search YouTube using Pasty Thompson quilter, as there's a singer too!
