I have the 6x24 you are talking about. When I first started quilting, it was what I started with, the omingrid. I have trouble using any other. Isn't that funny. I even got a 6 1/2 x 24, because that is what you cut your blocks, never could figure out why the ruler was only 6. But thats like the quarter inch foot, and you sew less. Lots of things makes no sense to me, but that is just me. If they mean a scant quarter, why can't they make a scant quarter, if you need 6 1/2 why not make them all that size. Oh well. I have the 6 1/2 and don't use it because its harder for me to see. We are such funny ducks. I would keep trying it, they are wonderfull. or is that only my opinion.
