Trompe L'oeil or Trick the Eye
I also had a go at illusion or shadow knitting tonight with the "Illusion Kitty" kitty face from http://chickybabe.org/driveby/patterns/chart.html. I doubled up a couple of rows, accidently, so mine looks like "Illusion Puppy" and you have to hold it at just the right angle to get the effect. I just hoped it would be a bit more stunning. The instructions were really easy to follow, though, because I find charts quite daunting and prefer the old k1,p1 style of pattern.
It's a warm night and I can hear a party, booming bass, not far away, but sleep beckons and my body will be glad to lie down. I will need to get into the painting of the new "Shed" tomorrow so that I can move in soon.
