What kind of a tea exchange do you have in mind? We are just wrapping up the Holiday Tea & Chocolate Swap over on the Swap Talk! forum. If you'd like to see the brags, the link is
here.
You are fairly new, so your best bet would be to post looking for a private swap partner. You would need to explain what type of swap you want, what the budget would be, etc.
Things To Consider:
-- Are you looking for a US / North American or International swap partner?
-- Do you have any allergies your partner should be aware of?
-- Do you want just tea, tea and sweets or something different? Do you want part of your swap's budget to be for extras?
-- Asking about stuff like favorite animals, favorite colors, etc. can be helpful in choosing a card so your swap partner knows the box is their swap box and for choosing paper to wrap gifts.
If you haven't already, I'd suggest that you take a look at some brag threads in swap talk to help get an idea of what a swap tends to be like.
I hope this is helpful. Have a great day!
