Well, for the black and white color group I have :
mat 1: 4 1/4 x 6 1/4 bazzill white, 1/16 layer black on a 5 x7 zebra printed paper. It has brad in the corner with a tiny bit of white fiber
mat 2: 4 1/4 x 6 1/4 bazzill white, on 4 1/2 x 6 1/2 black with a piece of zebra ribbon about 3/4 inch from the bottom, anchored with silver brads
And this seems to be what I tend to do over and over again with different combinations of paper and embellishments. Okay -- why didn't I just take a photo and post it? Wait -- I did this same mats for MK swap, it was a Fantasyland page kit. Maybe there is still a link to the photos somewhere.
I am determined to get out of this monotony. Maybe I'll check out pages posted on ebay. There aren't any photos on the mats.
