If you don't have the clothing items at home that some of the previous posts suggested , check your local thrift store, Salvation Army,Good Will......that way you won't be spending a lot of money and will still have an awesome costume!
This takes a little bit of time, but the final outcome is really cool. It's a great project that a child can help with.
Materials needed: New picture frames wire mesh scissors or wire cutters some type of thin flexible wire
I bought frames that would hold 2-3 pictures.
You will need to cut the wire mesh to fit into the frame. Take the backing off the frame. Place the mesh in the frame where the pictures would normally be placed. Then replace the backing onto the frame. That will hold the wire mesh in place.
Now,cut a piece of wire, feed it through the hook on the neclace, and now loop in into mesh on the frame. You do this with each neclace and you can do it with some earrings as well. (It won't work with earrings that have a post back) You can put as many neclaces on the frame as you want to. The size of the frame will determine how many neclaces it will hold. I like to use an 8x10 frame. Best to buy when on sale at your local arts and craft stores.
