We got the kids a couple of disposable cameras for their goodie bags. I'd like them to be able to carry them around their necks (so we don't have to carry them ), but they don't have straps or any "loops" to fasten a lanyard through. Does anyone have a suggestion as to how to make and attach a neck strap? They're only 7 & 5, so 'fashionable' isn't necessary. TIA!
