This half square pattern is now available as a companion to the Tunisian Pinwheel Square pattern. You may obtain the half-square pattern free, when you purchase the full square pattern. Buy full square pattern now.
This project employs the Tunisian simple stitch. However, a Tunisian crochet hook is not necessary, as the half-square is small enough that a regular crochet hook can be used. It is perfect for joining to the Tunisian Pinwheel Squares, on point, to make a larger project, such as a blanket, shawl, or bag. This is a good project for yarn scraps, as each of the 4 triangles can be made in a different color.
Also, if you want to make just the basic square, with the 8 triangles only, and no border, you can find the free pattern at the link below. ===> 2018 Free Version Tunisian Pinwheel Square
