Alright, you guys. This is what I have sorted out so far. There's still a chest of earrings back home that I didn't get to get my hands on because my sister was all over them, so those will have to wait for when she grows tired of them too.
1) Both the own pendants measure up to 3.5 inches. The feather is about 2.5 inches and the other one is about 2 inches. All the chains measure up to 17 inches at its longest.
2) Most of the chains in the second picture measure up to 9 inches at its longest. I don't have the necklaces for the three pendants at the side. I really don't know why. D:
3) Bracelets are both adjustable.
4) I'll clean the earrings before I pack them up for you, no worries. =D I lost the fuchsia heart from the second set from the second earring photo a few weeks ago when I was at a party, but the three remaining pieces make up fun combinations still. They used to be my favourites and I got them from Bugis (Singapore) at $2. 8D
5) The fox/flower/vines rings all fit small-medium sized fingers, depending on which finger you wear them on. I can wear them on my thumb, forefinger and ring finger. I think I'm a medium size. The rest of the rings are all adjustable.
There are no actual rules to the swap because I've never done this before and I really don't know how it's supposed to go. You can either make your own picture post and link me to them or post pictures in comments to this post or you can tell me that you're going to surprise me and send me random things. Comment with what you want and if they aren't taken up yet, they're yours! =)
