Here are the supplies I purchased:
•4- six packs of mini cordial glasses
•a plastic storage container- this one is about 3X9 inches
•one bag of thick rubber bands
In case you were wondering, I attempted to first make this with hot glue but the plastic doesn’t bond to the plastic. I also tried gorilla glue but the plastic container is bendy and the elastics pulled it all tight together, keeping the storage unit sturdy. The elastics were an easy alternative and barely show once the paint is put in the cups.
