I took the plunge and started on the off-white finish this afternoon. I also sanded and added some tung oil to the top. It was a perfect day for working on furniture - it was grey and super wet out! The legs I picked up at the dump look so much better now that they've been painted. I'll tweek the paint next weekend then shabby chic the cabinet.
I also penciled in the triangles. I'll work on painting them next weekend. I'm going with an overall off-white finish with grey, black, robin's egg blue, mustard yellow and then some triangles will be natural wood.
Here's the cabinet thus far. I think the off-white is definitely working!
Hopefully I'll finally have my cabinet done next weekend!
