Hey Teresa, good answers on FMQ - And leah day has a tut for beginning FMQ on you-tube that's worth a watch.

I bought a generic walking foot for my Pfaff and thought it was the problem -- But it was a combination of my fabric "dragging" and not being level with my sewing machine needle area, and the tension too tight... I didn't realize with the top, batting and backing, you need a larger stitch to go through and come back up without making it "pinchy"... Some machines you can adjust your pressure foot "Pressure" -- This helped alot! See if your manual shows a spot (dial maybe on the back side?) where you can fiddle with Pressure Foot Pressure -- Another You-Tube find !

Good luck and hope you find your Sweet spot for you machine.
