Here's a cute little snowman ornament that I made this week. I used acrylic paint to cover the inside, and then painted the outside. To seal it, I used a clear coat of glitter spray. A cute and easy ornament to make for the holidays! Happy crafting!
Edited to add: This is a glass ornament that I found at Hobby Lobby. I poured some white paint on the inside of the ornament and made sure it was all covered. I did find out that if you are not careful while it is drying, it will continue to run. I put the face side down as it dried, so that the front would still be covered completely. I painted the cap, face, and buttons on the outside. After everything was dried, I used a glitter spray to seal the paint on the outside, otherwise it would all scratch off.
