im gonna share a tip here that amanda taught me, incase others might not know -- this is especially useful for online sessions but also for maximing fund-raising trips back and forth to nookie's.
write 4 or so letters to yourself and stuff the tools inside them that you don't use that often but don't want to leave at home. i always have my slingshot, watercan, shovel and net in the envelopes while i'm fishing, for example...that way i can hold 15 things to sell.
