Terry saw this pattern on one of my Facebook groups and asked me to make it for him. The pattern is called Labyrinth Walk - and it is really fun! It does look 3D thanks to the fabric choices. It is only 9 blocks, made of 4 fabrics. The quilt measures 83 1/2" square.
There are 5 blocks (corners and center) that are made of 29 pieces each and are fairly easy. The other 4 blocks have 66 pieces each and are much more complicated! There is also a 6" black border - you will note that the upper right and lower left corners are cut off which helps make it more 3D looking.
I meandered in the black and grays with Omni black / gray variegate thread. I did pebbles (closely done circles of varying sizes) in the 3/4" white pieces with white thread and spirals in black in the black borders. The colors are gray and black - I took some photos outside and the sun/shade gave it a bluish hue.
