Using artists canvas as a base for terrain tiles?

[Norm]

I have used both artist canvas boards and artist canvas frames and neither were successful.

The boards developed enough of a warp that they did not sit nicely together and the frames didn't have sufficient uniform size and shape to sit nicely together and the interior needs support because the canvas does sag. Also the canvas being wrapped around the sides and being bulkier in the corners due to the folded meeting point of two edges did not help.

it sounds like a nice idea, but in practice, I think you need to buy the best artist materials, which will still not be ideal and you would have spent two thirds of the money that you could have put towards a purpose built mat. Just my take (after having attempted it).

How big do you want to go?

For 15 mm, I have not used a canvas, but a pinboard made out of cork (2'x3')

I have a couple of those too, for smaller boards.

I'm afraid of warping though.

Paint up the framed canvas however you want. Once it's all dry, you can cut the canvas free of the frame and contact cement it to an MDF board. Best of both worlds.

We use a similar laser cut MDF system made here in OZ, it uses magnets rather than clips to hold the tiles together.

Thanks for that link, these look great and are even .au based to boot.
