Just finished the last part -- shoring up the guitar, and guitar strap.
The guitar is the pink one out of this assortment:
Got it a while ago at Target just 'cause she's big on the air guitar, not for Halloween, but since we have it it's useful. Problem is that it's inflatable but pretty much impossible to inflate all the way, so it sags, especially up by the tuner part. So cut a wrapping paper roll in half, glued both halves together (one inside the other, a half-cylinder that's double-strength), covered the back of the new half-cylinder with pink ribbon that matches pretty well (not invisible, doesn't jump out at you), and then last thing will glue that straight to the back. (Want to wait in case there's some reason I need to deflate/ inflate again.) It clings to the neck really well and makes the whole thing quite strong without being too heavy.
Then the strap is just a black leather strap from my old purse that broke, with silver buckles and keychain rings to attach it. (The guitar has places to add that, flaps of plastic with holes in them, so I don't have to pop the thing.)
Ready!
