I sanded then primed but on a base coat then went to hobby lobby and bought 5 different shades of Americana acrylic paint and sea sponge. I went to lowes and picked s countertop and took sample withe to hobby lobby. I started with one shade sponging . When it dried I did another. I kept doing that till I got the look I wanted . You can add more of any color at any time if you want to. Once I got it like I wanted I put 6 coats of poly acrylic over the top that I got at lowes. I didn't use the countertop for 2-3 days. When I first did it I left something wet on and it bubbled but once the wet was removed it goes right back to normal. As time has gone on and it's cured more it doesn't do that anymore.

For a cleaner look, paint it all a shade of white similar to your backsplash. This kitchen uses butcher block and light woods for the furniture.

Don't - this is a better space for a peninsula. Any Island in this space must be tiny and can't be sat at. Unlike a peninsula. An island would just clog up your kitchen. We find that many of our customers think they want an Island, but what they really want is the best looking and functioning kitchen. An island in a room this size eliminates the possibility of a great design. I would first get professional help. Often initial help is free. And if you decide on putting something in the middle of the room make it movable. Like a butcher block table.
