1/4" quilting foot, originally uploaded by Ansis68.
I haven't used it yet but I'm really very excited and wishing I'd come across the mention of this accessory in my sewing machine manual before I started Amy's quilt. It was a happy co-incidence that Spotlight was having a 20% off all sewing machine feet sale in which I planned to get a walking foot (and did) so I got out the manual to look up part numbers (pointless, they're different now anyways) and discovered that such a thing existed. I think it's what they call a Eureka! moment.
The really brilliant thing about it is that it has these lines front and back (marked with red arrows) that show you where to start and stop sewing to leave 1/4" unsewn at either end if you need to attach more blocks. I don't need it for this quilt, but it would be so handy to have for other projects.
