I made my hot air balloon ornament, using a plastic Christmas ornament I bought at the 99 Cents Only store. There were some cute pink ornaments there that would be perfect for a girls mobile.
|Here is my version.|
** An alternative if you don't want to make a the basket out of paper is to use a plastic soda bottle cap and paint it brown. Hot glue the strings to it
*** If you are making this into a mobile, I would hot glue gun the cap of the ornament onto the ball so there is no risk of coming apart and being a choking hazard. I would also hang it high enough that it cannot be reached or pulled down by the child.
