Yes these are actually embroidered creations by painter Cayce Zavaglia. Switching from paintbrush to needlework wasn’t a walk in the park for Cayce. Unlike painting where he can mix her paint color to achieve the desired effect, wool comes in fewer color range. He was able to overcome it though. From his bio he said:
Progressively, I created a system of sewing the threads in a sequence that would ultimately give the allusion of a certain color or tone. The direction in which the threads were sewn had to mimic the way lines are layered in a drawing to give the allusion of depth, volume, and form. Over time the stitches have become tighter and more complex but ultimately more evocative of flesh, hair, and cloth.
Cayze is reluctant to call his creations ‘paintings’, rather just borrowed technique from drawings and paintings.
