I always have my golden watering can, my golden axe, fishing rod, bug net, and shovel. Other than that, I try to keep my pockets empty in case I get the urge to move around some flowers~
I always have golden can & shovel.
I really like to have free space, so those are the only things that are always with me,
but there are some things that i have placed around my town for easy access.
I don't walk/run with balloons, because I am afraid I'll trip and lose it x) Same with ice creams. @snoozit, has this ever happened to you?
I only keep my tools with me. The watering can and shovel are always in my inventory and I keep the rest in my envelopes. (sounds silly but it's an animalcrossing-thing, y'all know..). That way I don't feel completely helpless when I see a present floating around or a rare fish that desperately needs to get caught =)
I always carry my tools in letters - a silver watering can, a golden shovel, a golden axe, a silver net, three diving suits (I think they're the striped, pink and either red or white ones), a golden slingshot, a silver fishing rod, a megaphone and a stopwatch. I also carry any fossils and bamboo shoots I find around town until I sell them.
