I was wondering how it would look if you painted the little ridges in your cabinets a little darker. Microwave is so much better than the range hood! Do you have an outlet up there? That looks like quite a high space over your stove, how will you fit that in without having to hang it too high? Just cut the shelves off?
Soapstone.... that's greyish right? You could do a really cool tile backsplash that would look awesome.
The top shelf will stay (or get moved up or lowered so it sits on top of the microwave sleeve). The microwave bottom will be level with the bottom of the cabinet next to the range.
I removed the bottom shelf this morning.
I left the wallpaper on top of the cabinets. It was in very good shape and will match nicely with the wall color, which will be the same color as the top half of the dining room wall, through the doorway next to the stove.
