Since I recently discovered swap-bot.com, I've decided to give it a year and join in the fun that's going on there. They've got swaps and trades going for every item or subject ever thought of in a creative mind. There's even swaps asking to trade stories on "How you will survive a zombie attack"! And of course, more sedate being the tea bag swapping. But if you search for a topic or item that you want to trade or swap with someone else, you are sure to find it, and if not, you can start your own.
Another good thing about the site is that they monitor good swappers and bad. They have a system of earning 'hearts' for good swapping (this being mailing your items off in a timely manner, and mailing items that are good enough that you would want to receive them yourself); and no good feedback for bad swapping (not sending items, even though you signed up for the swap....etc.) will earn you bad ratings and get you banned from participating.
So far the swaps I'm signed up for are Bubble Swap (trading those vending machine toys that come in a plastic bubble....this swap is international, so I really hope I get one from out of the country); Slipper Swap (creating some slippers for swap partner); Stuffy Swap (sewing up a stuffed creature for a partner); Link Swap (swapping home page links for viewing), Angel Cat Swap (swapping cat ATC's); and Mardi Gras ATC swap.
I believe that being creative is more fun when you are making something that will be given to someone else, so I think I will enjoy swapping at this site all this year! I will post photos of items received.
