Too bad they don't make a walking foot that has that SID guide on it. That would be great! I like the guide for accuracy but it seems to push the fabric ahead of it when quilting. I have 2 of these as I wondered if there was something wrong with the first one I bought. It's like the guide is too tight against the fabric and "digs in". Perhaps the suggestion of pulling the fabric to the sides as stitching would help prevent that. Will have to try it.
