You can see the shelf at issue in the lower right hand corner of the above picture. A few hours of work by Handy Hubby and we had this.
I got lucky and found another knob like the others at our local hardware store. Then I need to paint it all white and it will blend in a bit more and seem more seamless and intentional.
Other than the knob (about $2), we had the wood and door left over from our old kitchen. Handy Hubby rounded it over with a router to mimic the drawers. I'll be sure to share once it's painted out - hopefully by next week!
I have a whole bunch of other tweaks I want to make in this room. Next up is a rug I think. Sofa will have to wait a few more months but I have it picked out I think.
