Hi Darlene,
I remember the pieces V is talking about. It seems to me they were in the beginning threads of the funeral designs thread. She used flat styro-foam and then cover with her cushions. Then she air-brushed, but you should be able to do it with your design master - I would use almond. If you are any good at all in painting or pastels, use those talents to put some shading in for the rounded joint areas.
Is it from a beloved pet? I assume it will be on an easel.
But there are other things you can do if it is flexible.
You could do something in a very large dog dish or other large container, and make the bone smaller with a brick of oasis. It isn't that hard to shape it, and then do as above. Use toothpicks for your mechanics either way. Then, do a spritely arrangement in an asymetrical design around the bone propped at an angle.
Hope that helps, when is the visitation?
