Here's the layout for Block 14.
And here's the layout for Block 15.
I also wanted to mention, for those of you who don't have a lot of solids, Kona charm square packs can be an effective way to get a bunch of them at once. (You should be able to cut four 2" x 2" squares from each 5" charm square.) Sew Mama Sew! just got a big shipment in and have the dusty, bright, dark, and classic colorways. If you click on the images on the RK website (linked above) you can see which colors are included in each. I would say that the bright colorway is probably closest to what I'm using. None of these packs include much gray though, so you may want to get a small piece of the gray solid of your choice separately.
