The makeup takes time, that is for sure. A couple of things do help. One is using good quality makeup (Mehron and Ben Nye are two of the best.) Another is looking at lots of pictures of clowns with well designed faces. For this you might go to Clowns of America International's website and look at the competition winners. There is a link on their website to other regional clown associations and they usually have pictures on their sites as well. Another site is
Pricilla Mooseburger Originals The site is for Pricilla Mooseburger, a former Ringling clown and costumer. You can not only look at the costumes for future ideas (I looked for years before I made that kind of investment, now I am glad I did, both glad I waited so I knew what I really wanted, and glad I finally made the purchase.) bit also look at the makeup of the clowns pictured on the site.
