Coat the wrist area with latex and add some cotton. Also fill in any bare areas on the fingers.
Ok, here's the fun part. When brushing on the latex it is best to put a lot of latex on the brush at first and then spread it out over the cotton. I have found that if you do not have a lot on the brush, the cotton will stick to it. This is a real pain in the Butt. After a couple of times you should get the hang of it. If the cotton, balls up on you don't worry, it adds a great decay look to the bone.


At the time of these photos I was using uncolored latex. After some advice from friends on the list, I now mix brown latex pigment to the latex before brushing it on. You can get the pigment at you local hardware store. Just ask the paint department. Remember that when the latex dries it will be darker then when it is wet.
Brush a coat of latex on the lower arm bones. Take a roll cotton and apply it to the bone as shown in the photo. Do this all the way to the elbow area. Then flip the arm over.
Brush a coat of latex on this side of the bones and also on the cotton.
