I'm in a Yellow State of Mind!

After the first coat of yellow primer my bookshelves are looking decidedly cheerful!

As you can see, the yellow primer is much lighter than the yellow of the wall.  Eventually all of the bookshelves will be that same darker yellow.  Here's a close up to see the difference in color better:

After painting the primer on the shelves it was much easier to see all of the areas where I either forgot to putty, or where the putty job was simply sub par. 

Giant gap where my shelf meets its dado cut.

Same spot filled with putty.

I've started actually painting now, I'll give you an update on how well my attempt to smooth out the shelves works once I slap a coat of extra shiny paint on top of it!
