One of the ideas online was to make marble looking ornaments by pouring different color paint down the insides of the ornaments and turning it ever so often so the paint would swirl/marble together. At the end you turn the ornament upside down and let the remaining paint drain out, which also helps in the marbling.
I also painted the outsides of some ornaments. I'm a fan of polka dots so the two I painted the outsides of were adorned with these.
After the paint was dry, I hot-glued the tops onto the ornaments and then piled on the ribbon with hot glue as well.
I also personalized the outsides of the ornaments with names and dates, as well as used a little scrapbook bling around the sides.
The ornaments that I painted on the outside were also painted with Modge Podge once dry to prevent the paint from chipping off.
