In my opinion, it's too complicated to use paypal etc., or at least, I wouldn't want to be in charge of a swap based on paypal-payings. It's always best to send the bracelets as a normal letter in an average envelope, where you can put the bracelets between two cards to stabilize the whole thing. Most of the bracelets, which got lost in the swaps I hosted, were more expensive sendings with tracking numbers etc. Those seem to have a "longer" way because of postal controls etc., so it usually takes longer for them to arrive. If you miss such a sending, they don't put it in your mailbox, but you have to go to the post office each time, which is impossible, when you have more than 20 participants. I think for the costs, it would be best, when some of the european participants (who in general make a half or more of all participants in international swaps) would just put one or two euros in the envelope instead of stamps, in case those are not available.

Can you just put some euros in the envelope?

I think what Arismende said is indeed the most simple way of swapping/mailing bracelets.
Coins have arrived here without problems, although it's actually not allowed to send money like that. It's not a big amount though, so we will not really get into trouble if we include a few euros in our envelopes.
I'm personally also fine with using PayPal.
And I think we should keep it voluntary. That worked fine in the past :-) I think every moderator that hosts a swap knows it'll cost a few bucks....

OK, that is good to know that I will be able to send an average postage from here in the States to another country

If paypal is an option during the next swap, I will definitely contribute one or two euros. :)

I agree, if I'm able to i will contribute a few Euros :)

I would like to participate to a bracelet swap even if I am a beginner
