Step 1: Squirt a little paint into a bowl. Remember you can always add more.
Step 3: Add in water about a TSP at a time, and mix with paintbrush. You will want it to have a nice pouring consistency, but not TOO thin. If its too thin it won't cover the jar as nice. It's no an exact science of course.
Step 4: Pour into jar.
Step 5: If your using a lid or rim go ahead and place it on now. I think it helps to kinda keep the paint from going on the outside, but it works for sure without.
Step 6: Now turn and tip your vase letting the paint swirl around covering the inside. If you've used way too much paint hold it over the sink to let excess paint drip out. Also if there are any bubbles visible from the outside just gently pop it with your paint brush.
Step 7: Remove the lid and wipe edges clean if needed. The jar will need to dry for about 1-2 days depending on how thick your paint it. I like to lay it on it's side and rotate the jar every 20 minutes or so for the first hour. This helps even out the paint on the inside. So it's not too thick or too thin on any side.
Now you have a pretty jar in any color you'd like! You can add ribbons, gems, or anything you'd like to spruce it up. Think about the possibilities here! Maybe this would make a great vase for the kids to make Grandma this mother's day?
Here are a few more times I've used this little method.
This last shot is from some kitchen decor I made, fake milk jars. :)
There you have it, one of my favorite easy and super cheap tricks!
