If you go to the store and look at the 1/2 in PVC and the end plugs for the 1/2 anything larger then that would work. Then you take the poles that you are going to fit the sticks down into to and drill a hole and put a screw through with a nut on the other side so they will not fall down once the balloon is popped.
Will see if I can find a picture of them. Will take about a week or so to get them out.
Also my paypal account is firstname.lastname@example.org
If you can do the personal transfer and do not indicate you are buying something so I do not have the big paypal fees that would be great. Also get me your zip so I can figure out what postage will be. There is a couple different ways to send them and depending on where you are will depend on the cost.
