uh, pretty hapazardly, actually. I've got cards in binders, cards in toploaders, cards in tins, cards in deck boxes, cards in longboxes/ETBs, and cards with no protection whatsoever in just stacks
Me too, lmao. My fancier cards are stashed away nicely but I've got loose stacks of cards hanging out everywhere. I hide them from myself to find for later. ヽ( ´¬`)ノ
