Free Quilt Block Pattern

The Vortex quilt block is a simple four patch design featuring half square triangles and a patch that is underused, (in my opinion) and that is what is known as a three quarter square triangle patch. This last unit is comprised of a half square triangle and two quarter square triangle pieces to make up the completed patch. (These different pieces are used in order that the completed unit keeps the straight of grain edge on the outside. This in important in order to avoid distortion of the pieces as they are handled.)

This quilt block is sort of an optical illusion representing a swirling "vortex" (hence the name of the block). I see a pinwheel spinning in the centre. All sorts of interesting arrangements can be made using this block over and over in your quilt. Two sample quilts are illustrated on the following page.
