Supermarket find

At my local Morrison's the other day I spotted these:

My initial thought was, "those must be useful for something" so at £1.50 for a pack of three I thought it worth experimenting. If nothing else we'd have some more cloths to use in the kitchen!

They fold out into three 40cm-squarish sheets. The material is about 1.5mm thick, matt white and with a felt-like texture but slightly stiffer. They're certainly cheaper than buying those felt squares you can get at Hobbycraft. 

So far I'm envisaging three potential uses:

1. As the water-absorbent layer in a makeshift wet palette (I'm trying this out and it seems to work with a layer of grease-proof paper on top),
2. Cut into suitable shapes as snow-covered fields for 1/300th scale winter games, and
3. Potentially to add a temporary layer of snow to the roofs of 1/300th buildings.

I guess the next job is to see how well they take to being coloured with acrylic paints. I'm not sure what additional uses that might open up but I'll report back here if I find any.
