I asked Amy about this window as I was not sure how to stitch the top part of the bottom ledge. I want to share the information with you. You need to stitch over two threads covering the brown line. The raised stem ledge will fit under it.
Stitch a couple of rows of continental, (with three strands of the thread listed in the guide), under the arch with the same thread used for continental on the sides. The bottom of this arch is not specifically painted for the small leaf-shaped points at the bottom tips. Just leave enough room to do one on both sides.
On all of the windows, do one row of continental on the sides of each window, (three strands), and two or three rows of continental under the arches. Amy suggests doing an extra row under the arches so there is no chance of blank canvas showing under the arches we will build on the top of each window.
If you are working on the bricks, check out the comments/tips under Glitter Glue posted on May 5th.
Have a great weekend.
