...so I can plant in them too!

I got the lumber for the bed frames:
The wood is douglas fir, purchased at Lowe's. My lovely neighbor and friend was nice enough to drive me there with her truck so I could get it home. I had Lowe's cut the wood to the lengths I needed to make things easier. Now it's just a matter of drilling pilot holes in the ends of the wood and using deck screws to secure them. Simple, eh?
