It all started with inspiration from a Brazilian gemstone book -- colors & cuts.
Then the idea came to use the "cracked glass" pattern found on the legs of a Chinese desk.

Then Bob modified it into a square pattern of his own. The desk cracked glass pattern has 11 pieces; Bob designed it using 13 pieces.
After ordering a variety of reddish & gray fabrics online, the block was finalized using 3 shades of gray & 3 shades of red.
So far, I have 6 blocks complete -- not sure how many more I will make -- it's fiddly & time consuming but what quilt isn't? Each piece is cut using templates -- trapezoids, one hexagon & 4 triangles -- plus two skinny rectangles with the top cut off at an angle.
