[Tango-L] What to do with a carpeted floor?

[Sergey Kazachenko]

Dear listmembers,

I am about to move to a new place, and it, sadly, has a carpeted floor.
What can one do to create a little practice space without ripping off
the carpets?
Any suggestions?

I vaguely remember someone (Eero?) saying something about using
roll-on vinyl for outdoor guerilla tango events, but can't find that
message anymore.

Thanks a lot,

Sergey
