Kawaii nesting envelopes, Matryoshka-style #4

Based on the Snow Ball swap by @streetjewel and modified with her kind permission...

SO! Round 4 of 6!

Got your round 3 envelope? Good! Put it, and a flat surprise in a larger envelope. Decorate the heck out of it! Now put on more stickers! More tape! More more more! Write the name of the swap on the outside of the envelope! Send it to your partner!!

Your partner will NOT open your adorable envelope, but will place it, and a flat surprise in a larger envelope, decorate the heck out of it, Write the name of the swap on the outside of the envelope! and wait for our final, 4th, round.

And so we will go for 6 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 comment to all rounds. =D
