I feel that the Creative Grids rulers are very "busy" - and require serious concentration when I use them.

One of my very favorite small rulers is the Omnigrid 4x8 ruler that is gridded in 1/8 inch lines. I also like the Ominigrid 3x18 that is gridded in 1/8 inch lines.

I use the tiny rulers from Rhonda quite a bit, too.

When I was cutting I Spy squares, I had clear plexiglass cut into various sizes and then used 1/4 inch masking tape on the edges to "frame" the picture. Some hardware stores were better about doing that than others. I think the cutter of them was cussing at me when trying to cut some of the really small squares (1.25 inches, 1.50, 1.75, 2.00, 2.25).

If one uses a lot of a certain size that isn't commonly available - 7.5 inches, for example - I think it is worth it to get a piece of acrylic or plexiglass cut to that size - than I don't have to "think" when squaring up a unit or block. It's also a good idea to label the size on each square!
