What are your solutions for this?
I had a handful of small mats that match some games like Doomlings. Nothing for MtG or anything.
Just received the Marvel/X-Men Dice Throne Kickstarter (after 18 fucking months) and underestimated the amount of space taken up by 10 large 28"x14.5" playmats.
Depending on how you prefer to store them, for really large playmats I like this 3D-printed holder. I have my table-covering mats in there.
