I was wondering if any of you do free motion quilting on your machines, on or off a frame? If so, have you ever done it using rulers like long armers, to get curved or straight lines when quilting? What foot are you using if you are using rulers? I have seen a modified fmq foot for use with rulers, but it is $70.00 which is a little above my budget. I almost forgot, I have a Pfaff Quilt Expression 2.0 not the 4.0. Any input would be appreciated.

Thanks
