Hi Deb, here's how one Hometalker did it for less money! https://www.hometalk.com/22724489/gorgeous-shiplap-at-a-fraction-of-the-price
Deb: maybe this will help
The easiest way that I have found to put up shiplap is to use this product from Home Depot. It is a preprimed material and each board overlaps so you can't see any wall in between the boards. It cuts easily with a chopsaw and if you use a nail gun to attach it to your studs the work goes quickly. It comes in different lengths so you can buy what suits your job the best. You can chose to fill in your nail holes and sand smooth before you give it a final coat or two of paint. I have this in my kitchen, one bathroom, and I used it in another bathroom on the ceiling.

Here is some helpful information:
I put shiplap as an accent wall in our bathroom with finishing nails into the studs. The primed shiplap was really affordable. I was even able to have the pieces cut at Home Depot, so it was a simple project!
