So I had my inspiration and my color swatches. Before painting I got my tarp out and taped the door frames so it could stay white. Taping is tricky so take your time. Some tools I used were a mallet to close my paint cans between dying because it wouldn't be good if they dried out and also I like to give the cans a little shake before opening them to make sure the color is mixed up good, a light so if the sun starts to fade you still have a way to see, different size paint brushes to use on different sections varying in size and of course your paint colors!
Then you just go for it. I hand painted every layer two to three coats each depending on how splotchy it is/you want it to be. No right or wrong way of doing this because it is yours. I decided to draw on my wall a rough outline of where I thought each mountain should go starting at the floor and working up. Then I painted it from the top working down going from lightest color to the darkest because then if I made anything bigger than I wanted or painted out of the lines the darker color I would paint next would cover it right up.
Layer by layer I grew more and more pleased with it. I would say painting time would be about an hour for each color since they are each a few coats while drying time was varied depending on the size of that mountain range. Overall a long but fun project that I am so excited to see every time I walk into my house.
Thanks for reading! TTFN!
