Any hints as to de-memorying it when I take it from the box later today and slap it down on my new 4x8 table?

warmth. Set it out and let it reach room temp.

I used double sided tape (stuck the mat to the table) with a few boxed rolls of media on the ends overnight when I got my cutting mat. It worked out well, nice and flat.

roll it up in reverse

I suggest 2 fine looking naked chicks sitting on the sides......24 hours should do the trick Bogie.

Bogie, when I bought mine I left it rolled in the box for several months before deciding to give it a try, that sucker had some serious memory curl to it, reverse rolled it up tight and tied it up then set it out in the sun like that for a couple hours, presto layed flat on the table and has stayed that way for about 4 years now.

We just let ours warm up to room temp and they flattened out after only 2 days. We then taped (double-faced) to the table.
