Blocking a Needlepoint
 

Does anyone have a blocking mat for needlepoint that I could beg, borrow, steal or buy cheap? Or know someone who could block it for me (preferable).

Since I probably won't do another needlepoint any time in the near future, buying a good mat doesn't make a lot of sense and I'm too cheap to waste money on a cheap mat, plus I'd have to buy two sets of the tiles since this is a large canvas.

It's Easy!
 

It's pretty easy to do. All you need is a flat piece of wood, slightly larger than your canvas and some tacks.
Soak your canvas, stretch it and tack the two upper, lower or (same) side. Stretch the other two corners
and tack the one corner at a time. When it appears to be square tack the last corner.
After it dries, it should be perfect.

Not sure if this is what you wanted, but hope it helps.

Sadly, I know how to block it. Just don't have anything to block it on and I really am trying to avoid buying even a piece of plywood for a one -time thing.

Picture please. I can imagine what you have done is beautiful.
