I don't think we can ever have enough good tutorials. The basic premise is terrific. I think a LOT of people will benefit from this - You might include a comment about how easy it is to flip or tumble a texture (even Irfanview can do that - it's free and even new-bies shouldn't be hesitant to use it) to add some variety and perhaps tweak the base colors. Do you "weld" the props using Export-&-import as well?
