I have the June Taylor square it up ruler with the opening and I love it. I even have the 4 pack set of squares from Wally and they are great. I'm sorry others seem to not like them but it could just be that I'm so new to quilting that these are all I know and haven't had any problems with them. My 6 x 24 ruler is the Fiskars that came in a set from JoAnns of the ruler, mat and rotary cutter. Haven't had any problems with the rotary cutter either. I found replacement blades for $1 ea at the Current Outlet before I left Colorado and took all they had off the shelf. These blades are about $6 each normally. I got really lucky and I'm stocked for a while. Just bought the Brother XL-3750 sewing machine. It works perfect for me. Don't need anything big and fancy. This straight stitches for piecing and comes with an extension table and foot for free stitching for machine quilting. I love it!!!
