Here are the things I sent away in my package for the Odd Duck of Swaps "Day of the Dead" swap. Sorry for the horrid pictures. I can craft, but I can't photo.
A Catrina (dandy) skull, complete with a flowered church-going hat. I used the Lion Brand Felted Skull pattern, but I used Caron One Pound yarn which can't be felted. The hat I made up, using Cascade 200 in Amethyst. For the flower I used Zealana Organic Cotton (limited edition, no longer made) in Sunflower and Bluebell.
A decoupage box, containing pictures of people running with skull heads. The girl I was sending my package to is a track and field person.
I also included some cookie dough bites, chocolate-and-candy-coated sunflower seeds, a wee packet of Nutella, some skull and crossbones facial tissue, and a little skeleton wooden toy that I painted to look like a day of the dead guy.
