You can put tons of things in the clear plastic ornament. My fave is swirling a couple of colours of paint together inside. :)

You can google it, but I think I rinsed out the clear ornaments with rubbing alcohol, let it dry. Then added acrylic paints one at a time. Swirl it around to cover ornament & let excess paint drip out by putting in disposable paper cup!

Hello. I always like to put photographs inside the clear ornaments- it’s tricky to size it perfectly curl it up and then unfold it with a skewer.

One of the most popular clear ornament ideas that I see is putting polyacrylic inside the ball swirling around emptying it out and then put in glitter inside. That way the glitter is always stored inside and will not flake off..

You can also fill them with confetti, garland, even battery power sting lights- you can use colored tissue paper in them, shredded metallic paper, etc.
