For a total of 6. I won the Fons and Porter ones at the 1st guild mtg I attended.

and
1 mini that I had forgotten about until I saw carolaug's post.

Just one (that I can find)
it is 17x23.
Had a smaller one, havn't seen it in a few years.
Had a real big one, loved it, but it got left in the sun in the back of the car. Got all wanky, had to toss it. They mean it when they said, it can't take the heat.

That's what I'm thinking. I only have 2 also. ;(

Thank goodness - I thought I was the only one.

Wow, do I feel like I'm a bit behind ya'll here! LoL
I have 2 but can only use 1 as my lovely dad left one out in the sun during a move and it got all bubbly in the center of it. I need to cut it down to just the usuable parts, that would give me some smaller ones. Both are 24x36 self-healing. The one I do use is double sided and I do flip it over from time-to-time just for a change of color. :-)

3 and it's enough for now...used only 1 for yrs
