This is something I made quite a while ago and always wanted to show, but forgot.
Last time I was in Japan I saw this really awesome keychain-thingy in Wonder Rocket.
It was a plastic ball with moss and fake roses in it. It looked awesome, but was like $10 and I wasn't really willing to pay that.
When I returned home I decided to just do such a Mori Girl accessory myself. I already have tons of fake flowers, leaves, moss and other things like this at home because I like to do small accessories, mostly necklaces and headbands, from time to time. The only thing I needed was the plastic ball with a hook so you could actually attach it to something. Luckily I found something like this on Ebay, so instead of paying $10 for it, my only expenses were around $1 for a plastic ball and it turned out to look pretty close to what I had seen at Wonder Rocket.
That's the result:
Creating these was easy as all you need is the plastic ball and stuff to put inside. I used fake flowers, some pearls and moss to put inside and a bit of lace band for decoration, but you can basically put almost everything inside and arrange it nicely.
I wish I had more time for crafting....
