Hello! I'm almost Canadian -- or at least I grew up in Alaska and now live in the Seattle area. More Fir here than Pine
My usual first stop for on-line buying is eQuilter, they have a ton of free patterns most of which are based on panels of coordinating fabric. Didn't have anything come up for your specific fabrics, but you can look for similar themes or block/panel sizes:

Jenny Doan of the Missouri Star Quilt Co has a nice video and there are other directions on how to make a single large panel into a quilt like you are looking through a window. (try search on attic window panel quilt)

I did an Attic Window a year or so ago (and need a better picture). In mine I used post-card sized blocks of fabric in an Attic Window frame, along with black sashing. Supposed to give the look of those old black-paged scrap books.
