Whoops! I missed day 7. So belatedly let’s look at All Rolled Up’s dry erase cards:

They come in two sizes.

This Staedtler Lumocolor correctable marker was the one they recommended — it comes off with a bit of elbow grease, meaning it won’t just be wiped off by mistake, and I could prepare tiles in advance.

Two packs of cards and a marker cost me a little over a fiver — great value.
