Begin Filling in the Area
Since the area above the arch is the main focal point, we chose a unique herringbone pattern.
To start this pattern, apply mastic to the first section and set the first full brick in the upper-right corner on a 45-degree angle (Image 1). Mark the smaller 45-degree angled pieces to fill in the gaps and cut them to size with the wet saw, and set them into place (Image 2).
Start working the herringbone pattern out by using whole bricks as far as you can. When you come to the edges cut the smaller pieces with the wet saw to fill in the spaces along the perimeter. Continue to work the pattern with whole and cut pieces of brick. For areas that aren't big enough to spread mastic, you can apply it to the back of each brick one at a time.
When you reach the top of the arch, lay a brick over the open space and mark (Image 3). Cut with a wet saw and lay the cut pieces. Continue on to complete the herringbone pattern.
