Here is a picture of the prompt for QAK ‘s (quilt artists of Kentucky) second 12 by 12 challenge quilt. The photo made me think of Esher’s art work and a fear of heights. It took me awhile to figure out how to draw a Penrose stair.
Next I cut it out of peltex and then fused fabric over it. The next step was to satin stitch the fabric edges.
Then then blue organza was added and next a layer of batting cut out where the organza would show. The quilt was backed with a silken taffeta fabric in Prussian blue. All the inside edges were stitched down and then straight line stitching was done without marking or measuring. Here is a picture of the finished quilt.
