I've started playing with her, and had a lesson at the dealer. Ironically it was back at the dealer on the weekend [my actual birthday] having a new bobbin winding unit installed, as mine was faulty. The combination of sick children, birthday cakes to bake, and a tired me has meant I haven't actually SEWN anything with it yet. And of course I'm itching to.
What do I think of it? In a word, WOW. I've never owned a top end machine before and it can do a lot I didn't think was possible with a sewing machine. I can see this Pfaff and I are going to have a long, productive relationship. I feel I need to give this machine a name, but what? All suggestions greatly appreciated in the comments.
