I started by searching google images for pictures of all the different Lego Batman characters I wanted to do. Here were the ones I had thought about doing:

Now that I had the images I needed, I was ready to get to work on painting the jars. I had first planned on painting the face color on the outside of the jar. But then I saw this great post on Make It and Love It where she painted the inside of baby food jars to make pumpkins for Halloween. I knew this was the way to go so that when I added the face details it wouldn't chip off the paint on the outside.
So, I got to work painting the insides of the jar. Her tutorial is so well written, I am not going to bother repeating it. I did exactly what she did. I did take her advice to not add too much paint and allow them to drain for a while. I put the jars upside down in a small dixie cup to drain for about 10 minutes each. Then each jar was allowed to dry for one full day.
I used a sharpie to draw the details and painted all the colored parts. If I had to do it over I would have drawn all the details with different colored sharpies and not tried paint. The details were so small it would have been just easier to draw everything rather than trying to paint. I ran out of time though and didn't have all the right colored sharpies.
I painted the lids the color the hair would be. I added "hair" details and masks with craft foam I cut out and hot glued on.
And here is how they turned out:
I think Mr. Freeze has to be my favorite. I ended up using an upside down candle holder to make his helmet and straws and rhinestones to make his breathing apparatus.
This idea could be adapted for any Lego themed party. These took a long time, but they were really fun to make.
