Even though I have probably enough good, light balsa to get me to the "finish line," I'm always on the lookout for more. Can you relate...? (Actually my son, Robby refers to the balsa supply here as "his inheritance.")
I just returned from a "honey-do" trip to the local mall, and after getting what Marianne wanted (dish clothes and shower curtains...) I went into the Hobby Lobby store. I very often go there in search of the odd light piece of balsa. Imaging my surprise when I found several really great sheets of wood. More surprising was the fact that a couple of the sheets had some very minor damage to one edge and the manager (I guess) was more than happy to mark the prices on those pieces down significantly (try from $7.00 to $1.47). The damage was very minimal and the vast majority of the sheets in question can be used. Nice find!
So, the moral is, if you are out shopping and there is a Hobby Lobby store near where you go, stop in and check out the balsa bin; you might find a gold mine of light wood, and you just might get a discount on some of it.
Note: I also check the local Michaels from time to time for light balsa, but in recent years the pickings there have been slim.
