I never got much info on the videos. I didn't find anyone who actually had the dvd to tell me which rulers they used in it. I did order it nonetheless. I'm just waiting for it to arrive. I ordered it through a friend of mine who since had a family emergency. I'm sure when she gets back I'll have the dvd and can follow up with info.
I did read a review this morning on the HQ sit down forum that Disc 1 helped her a lot. It is basic info - tension, etc and on how to properly use the stitch regulator. She said she got a lot out of it but she has a HQ. Most of that info is machine specific for that one imo but the ruler one should be good for any sit down machine.
