I'm Liz, in the US and I claim LizzieMcGuire for kool-aid, candy and knitting magazines.
I don't really have any specific countries in mind, I'd be happy to receive from anywhere!
*Postcards- Especially featuring architecture. I find American stuff so bleh. I would love anything with European castles and churches, or Asian shrines, temples or gardens. Or even anything depicting the local lifestyle, like fishing or farming or anything.
*Old maps- I like to see how different civilizations evolved.
*Dolls in your country's traditional clothing.
*Vintage buttons or beads
*Yarn (I'm only really familiar with acrylic, but I'm eager to try something else like bamboo, silk, or alpaca...)
*Fabric with prints usually attributed to your culture
*Coffee or tea native to your area.
origami or washi paper
bento boxes and accessories
I've seen somewhere online that a Japanese company makes double ended crochet hooks, those would be way awesome too.
