Based on the Snow Ball swap by @streetjewel and copied from @sebastian122 .

SO! Round 1 of 4! DO NOT SIGN UP UNLESS YOU CAN COMMIT TO ALL 4 ROUNDS!

Get yourself a SMALL envelope (the smallest the USPS will allow is 3.5X5), all out decorate it, and put a branded, small surprise inside (think mini memos and/or flakes for this one.) Put the swap name above your partner's name in their address so they know to NOT open the envelope! Like this:

KSU: Nesting envelopes, Round 1
J. Quin
123 Anywhere Street
etc.

Mail it to your partner. There is a thread in the forums for people to comment when they have received their envelope.

Your partner will NOT open your adorable envelope, but will place it, and a branded, flat surprise in a slightly larger envelope, decorate the heck out of it and wait for round 2. THIS IS IMPORTANT! You can be rated down for opening these before the final round.

And so we will go for 4 rounds. At the end of which time you will receive, chain letter like, a pretty, large envelope full of special envelopes and nifty surprises!

Please do not join if you're unwilling to commit to sending out all rounds. =D Other rounds will start when everyone has received the previous round.

This is sender's choice because you do not know who will wind up with your envelope. Branded kawaii only. Mailing time is one week for this first round since we should all have them ready to go out by the time I assign partners.
