Some of you might remember my guard tower project, from my "wall tutorial" topic, somewhere in this section. For those not familiar with it, here's a picture showing the tower:

I want to add a wooden floor to that the upper part and I'm not sure what to use. The first thing that popped into my head was balsa wood. It's light, easy to use, easy to work with and looks pretty good imitating wood. Almost ideal. But there's one thing that bothers me. I want to make a mold based on this tower (actually two molds, one for the lower part and one for the upper piece) and I'm not sure if the floor cast in dental plaster (that's what I'm going to use for casting) will look like wood. Basicily I'm wondering if balsa wood has a good "grainy" texture. I've tried brushing it with a brush to try make it look more like realictic wood, but I'm not sure if this is a good idea. Another option is to use thin sheets of plastic, cut it to strips and than use a dental tool to scribe the characteristic wood texture. I've never done that before, so I'm not sure how it is going to look.
So if you understand what I'm talking about and have any ideas on what to use, I would be more than grateful if you could post your suggestions here. Also if you have any pictures of finished dioramas that use a lot of wood elements and know techniques to achieve realistic wood texture, that is easy to copy using molds, feel free to post. Thanks in advance for any help,
cheers,

EDIT: ups... forgot about the photo. hopefully you can now see it.
