Spinning / Rotating Cutting Mat

[redcaboose1717]

Because I am new to quilting, I need some advice about purchasing one of these Spinning / Rotating Cutting Mats. What I would like to know is what brand you purchased and what size ?

I am thinking about purchasing the Olfa Brand 12 x 12 one.....mainly due to the fact that it isn't as expensive as the larger one, although if most of you have the larger one I would appreciate any info you have as to why you purchased the size spinning mat you have.

If you have the Fiskars brand rotary/ spinning mat, I would love to know if you think you should have purchased the more expensive Olfa brand.
These mats are out of stock here at MSQC at the present time.

Thanks so much !
