For some reason the bottom shelf wouldn't really take the stain--not sure why, as it's the same exact type of common board as the other two shelves, bought at the same time about 4 years ago. It's like it had some sort of sealant on it that prevented the stain to penetrate, but I'd given it a good sanding before I installed it, so not sure what's up. Happy to hear any ideas--I guess I could flip the board and see if the other side takes stain better, though that side will require a lot of additional sanding because it still has the deep bracket outlines from the common board's prior life as a shelf for DD. I haven't put the poly on yet as I'm debating whether to call the project finished or to try and figure out a fix for the bottom shelf. I know DS won't notice and it'll be covered by books anyway, but I hate that everything else took the stain so well such that the bottom shelf really stands out.
The 3 shelves and the underlayment backing I had on hand from a previous project; so the only costs were the 3 stair treads I used for the sides and top and the stain. Sturdy bookcase for about $65 or so.
