The shadow box in my"Country Quilts in a Day" by Fran Roen is totally diff than the one at the site above. Roen's is squares..each is made up of a solid triangle and a triangle of strips--using 5 fabrics total. It uses the 'speed technique' of cutting the triangles from the 4 strips sewn together...and sewing to dark solid triangles. Very pretty. I could scan a pix, but not sure I could upload it! lol
