My patern making isn't great yet, but this one wasn't too hard as it came from an old photocopy joke and didn't need much doing to turn it into a pattern. I like it because it's sooooooooo spoooooky, if you do what it says and stare at the dots for 30 seconds then look at a blank wall and blink fast, the face of Jesus will appear.
try it and let me know if it works for you.
Keefie.
