I have some remnants of old tent floors from some Eureka Timberline tents that I've hacked up.

How much do you need. I also have some tarp pieces from same tents.

Send me a pm if you're interested. Or I can whip you up a stuff sack pretty quick if you send me general dimensions.
I've been using them to replace the worn out stuff sacks of our troop tents.

If you think you can, you can. If you think you can't, you can't. Either way, you're right.
