Many pillow covers are turned, rather than having a binding like this one does. We love how the binding adds a beautiful finishing touch. In some ways it makes construction easier, too.
The pillow top is made from 3″ fabric squares. You may already have a nice selection of scraps and such in your stash to choose from.
Once completed it fits a 12″ pillow form.
The tutorial, from Corey at Coriander Quilts, walks you through all the steps.
