This is what you could do before making a final decision. I chuckled when I saw the hostess of "Design on a Dime" do it on the show today. I DO this ALL the time. You should see how quickly I can "remove" the peninsula in our kitchen with the erase tool in paint! lol
Take a picture of the space you want to renovate. Find images of items you think will work in that space. Modify the pictures in paint to the correct size of your image, save and paste those images to your initial picture. Be sure to save each image so you can decide which you prefer.
Our exterior AND interior needs updating. I can't tell you how many designs I have for our house done this way. My hub has no pocket expense when I redesign our house this way. And this DOES include types of shutters I want for the outside of our house. It also includes changing paint colors of rooms, too. You can only imagine when a salesperson comes to our home and I haul out my "virtual plans" of our house exterior/interior. So, Michael, try this after checking out companies and gathering their images to see which one looks best. Best wishes to you with your new wooden outdoor shutters!
