I have the OLFA rulers which I use and will be using on the OREGON QUILTING TV programs on public TV here in Western Oregon. People will eventually be able to request that they be shown on their local public station.
I don't make flying geese but use ALL the square up rulers. They make the sizing of blocks so much easier and are consistant.
GOOD ADVICE from Dolphyngyrl use rulers from the same company on a quilt.
