I have an assortment of cutting mats
a) a Martinelli that is reversable yellow or purple - very expensive
b) a Fons and Porter - won at the guild rarley use as it doesn't have a grid on it
c) an Olfa - the orginal one I brought from Canada
d) a huge white plastic one that came with my Horn table - I use it to cut large pieces and it is true if you cut in the same place it gets a groove ( a newer quilter came over and christened this one at the 15 inch line )
e) a rotating 11.5 or 13 inch pad - I use this beside my sewing machine a lot - most likely gets the most use and an Olfa I brought from Canada
It is nice to have a variety of mats to utilize from different projects. It would be perfect if my sewing table had a recess area for my mat to sit in and be flush with the table!
