So many I can't remember. Some I've even made up on my own.
One of my favorites was from a cross stitch and called Cherokee Star. I printed the picture of the cross stitch out and it came out about a 2 inch square. The four little blocks in the center were about 3/8ths of an inch square. I had to use a strong magnifying glass to see them well enough to sketch them out on graph paper.
