Weird question, I know. lol. Let's just say a craft project is involved. 
So, from vaguely remembering my own children's placentas and also looking at a few pictures online, here's what I'm seeing.
Fetal side: Dark, burgundy-ish, smooth, with lots of dark veins coming out from the cord.
Cord: White-to-blue, slightly translucent.
Maternal side: Rougher than the fetal side, slightly "lobe"y, same burgundy-ish color.
Overall average size: somewhere between salad-plate and dinner-plate sized.
ETA: Ok, I finished the craft. How'd I do?
