I have 2 shape n cuts and believe it or not my 1x6. Love my little one.

Probably the 6 x 24 and then the 4 (4 1/2?) x 12, then the 6 1/2 square.

6.5x24 it's always my first cut

6.5 x 12.5 and 12 in. square. I have the 6 x 24 but don't use it as often.

I would be lost without my shape cut 1/2" grid ruler for cutting strips and squares.

iT'S A TOSS-UP BETWEEN THE 6x12 and my Shapecut.

6 1/2 X 24 and 4 1/2 X 14 on my 30 X 36 mat

6 x 24.

My absolute favorite is my 4 x 14 yes, odd numbers. When I broke my first one I immediately bought a new one.

I use 6 x 24 or 8.5 x 24 for squaring off quilts ( in conjuntion with a large square ruler), and for cutting borders.

I use all size squares to square off blocks, I like to use the one closest in size to my block size.

The one I can find at the moment
