There are a lot of thing you can do.
Make a head band with 4 of them. You will need a headband that has the sprial wires on them. Pull off what ever is on the end. Stick 2 of the Mickey shaped stickers to a 5x7 card, ( or old ceral/poptop box) and then CAREfull trim around them. Now place them face down and lay the top end of the sprial wires on them, in the center. Peal the other 2 stickers, and aline them and press them on. You will have a headband with "Antenn Mickeys" that wave when you move, or in the breeze. You can use an acrylic sealer to make them more water resistance.
Make a necklace. Same idea, but use a long piece of 1/8 inch ribbon. Measure how long you want the finished necklace to be. Add 8-12 inches on each end to tie in a bow in the back around your neck. Find the center and mark it. Layer the ribbon between 2 stickers. You can have as many Mickeys on this as you like. Make sure that you have the ribbon only about 1/3 of the way down the sticker so it will hang "ears" up.
Make hanging Mickeys. Take a loop 3-4 in loop of 1/8 inch ribbon and fold in half. Peal a sticker, fold ribbon in half. Press in place, and add a sticker on top. This makes a Mickey sandwich with a loop between the ears. you can use thin wire, but ribbon is more flexable. Make sure that you have enough length in the ribbon so the loop is at least even or a little above the top of the ears. These can be used as earings, or another way to make a necklace, or as pull tags on a zipper, if you thread the sticker through the zipper tab before you layer them together.
Decopage(misspelled, sorry!) them to something. A purse, backpack, shoes.But make sure you seal the stickers only if you want to make them non removeable. There are several products at
WalMart/craft stores that seal stickers/paper to stuff. You will need to do a little research on this. But it can be done online.
Do you have a place on the wheels of your chair that you could stick them?
Or on foot pads? The handles?
Get some cheap lime ribbon and make a big bow. Or wrap it around the handles/arms of your chair, or even weave it in and out of the spokes of the wheels, if you can.
Hope this helped, will think some more.
The head bands with antenna can be found at a lot of party stores, and sometimes at a Dollar store. Or you can just use pipe cleaners and a head band. If you have a lot of them you could make a "crown" of Mickey stickers standing up off the end of pipecleaners that have been wrapped around a head band. Make sure you bend them in half,unbend, place the headband on the bend and then wrap the pipecleaner around to the top of the headband,twist, and bend both sides upward. Stick Mickey stickers on the top. Since you have both ends pointing up you could make a WWW shape with stickers at each top. Did that make sence?Hope so!
Best of luck crafting. and have fun!
