Below are some links to tutorials done here on the board by Cutebuns. One block wonder is sometimes called a hexagon quilt as well. That, stack n whack and 4 patch posy are similar in that they all use repeats of the fabric. Look at the pictures in the tutorials for a better explanation. :D Cutie's tutorials will walk you through the entire process, but I put some pictures below for a quick reference.

Here is a picture of one I am working on. You cut six strips of the same repeat, then cut them into triangle shapes.
