Thank you everyone for your input and advice. I found the feed dog switch - I had used it to switch over to embroidery, but didn't realize that was what I was doing :mrgreen: !
Also, I think that my stabilizer was too heavy duty and my hoop probably was not tight enough. I didn't realize that the tightness of the hoop could make a difference. I did however hear the needle struggling a bit with the stabilizer.
Off to try it again tonight - with a lighter weight stabilizer and a tighter hoop!
