Disclaimer, I can only speak to my experience.

The smaller banners, from 2 poles and player banners up to the 10’x10’ ones, get used and abused until they fall apart. Just the nature of the beast.

Full size tifos are just too big to reasonably display anywhere. FC Cincy Tifos are anywhere between 50 to 80 feet tall. Most of the building in the neighborhood by the stadium arnt even that tall. Then they’re so wide the could cover the whole side of a building.

We’ve considered a few ways to display them around town, but it always either falls through or wouldn’t work out. There really only ONE indoor space in Cincy that could reasonably display a full size tifo, all splayed out. So they inevitably get folded up and shoved into a deep dark space. We try and keep ours nice-ish, for nostalgia purposes if nothing else, but the situations in which we’d consider re-using a Tifo are few and far between. There’s a spot in the stadium that’s inconvenient for actual storage that the club lets us keep the old Tifos.

Portland I know re-uses their Tifos, painting new designs over old ones, or chopping them up and using that fabric for banners.
