I don't usually show these off, but to send out most of my plushies -- unless I need a bigger package --, I make envelopes out of scrapbooking paper, stuff bubble wrap inside for durability, and send 'em out.
I like making envelopes. I think it's worth the time and effort. X3
The flowery one in the middle is glittery.
EDIT: Edited because I apparently can't spell 'happy'. o_o;
