I've found a new kind of logic puzzle called "Stitches." The basic idea here is that you start out with a square grid. The edge information numbers at the sides tell you how many "holes" must appear in each row and column. These holes are linked with small lines called stitches. Each hole is linked to an adjacent hole, either horizontally or vertically. Squares that will remain empty are marked with X's. The object of a stitches puzzle is to correctly place each hole and the "threads,' or lines that link adjacent holes.

I've also seen Youtube video links that give tutorials on how to solve Stitches puzzles. You can find these by entering "stitches tutorial solving a puzzle" at the Youtube home page.
Please feel free to share your comments. Certainly Stitches is a fascinating and intriguing puzzle.
After reading my previous posts about Stitches logic puzzles I realize I need to add other points about these puzzles. The grid is divided into regions called "blocks." Each block to must be connected to the adjacent blocks by stitches. Also, there can only be one stitch linking 2 blocks. Two holes that are horizontally or vertically adjacent and part of the same block cannot be linked by a stitch. You'll notice that some squares cannot have holes for this reason, and thus those squares must be marked empty with X's.
