portion of original post from Rettie V.Grama "We will start the trade by sending a pair of Pot Holders from me to the first one that signs up. It will be sent in a brown envelope with a second envelope inserted with my name and your return address and 4-48 cent stamps attached for you to send me a pair of Pot Holders."
Swap host will send to Trader #1
Trader #1 will send to Host
Host will forward to Trader #2 etc.
The way I read it is all potholders will be sent to the Host, my guess is that this is to insure that no one sends and doesn’t receive.
I hope this helps, there has been problems in the past of people sending their packages and not receiving anything in return so now the hostess/host of the swaps are doing their best to try to prevent anyone from being disappointed.
