There are a bunch of ideas here: https://happydealhappyday.com/clear-plastic-ornament-balls/
I've filled them with dried flowers from special arrangements. A fun way to keep them forever!
Roll a photo of friend or relative's house that you cut out. Stick in the top and let it unroll. Add artificial snow and tie a ribbon around the hanger. Cool gift.
Hi,I would dip them in gold or silver glitter and then string them into a circle. I would stack circles on top of each other as I create them a little smaller than the first. Stack them. Add some greenery also the faux votives or a faux pillar candle in the middle of the concentric circles. Voila!
Remove the caps and stick stuff in the little hole, like glitter, feathers, etc. Replace the caps, add a hook and hang.
