not mine, saw in the Texas Guilders group on FB.  thought it was great optical illusion.  She said it was a kit she found in a quilt shop.

That is awesome!

I wonder if they used both sides of the fabrics on that.  Hmm.  

since she purchased a kit, I'm guessing the shop (or maybe the fabric company) basically used an entire fabric line (as they used to say on cereal boxes re toys "collect them all!!")  I am intrigued.  I put it in my quilt ideas OneNote notebook.  Maybe at some point in the future.  It would require a trip to Gibson's to be sure - grin.
