I have a rainbow sarong that I try not to ever wash as my table-cover, which never gets wrapped around a deck, but folded carefully along its old fold-lines. Each deck has a watered-silk square scarf about 50-70cm along each side (70cm for preference). When I wrap, I lay the deck diagonally across the very corner of one, fold the tiny triangle up, roll the deck once, flap one side up to double with the other side, roll the deck once more and flap back so that the deck has even thickness, then keep flipping in that second direction until I have a long deck-width tail hanging, then I wrap that around the little bundle until just the end is looks, and push that end under the wrap so that it all holds together. I like to have nice silks for my decks, and I'm fussy about colour (it can be any colour, but the tone has to be right). I have a few velvet bags (beggars can't be choosers) but they're second-best, and are used for less favourite decks. A few sad specimens are in their original packaging, either because I haven't found good silks for them yet, or because the decks aren't significant enough to me to be worth a major hunt for a silk.
