I have not before but I am going to in the future. I just took a class at my LQS where we used 3 coordinating fabrics. Most of the ladies used the fabrics from our current BOM that is going on. Because I wanted shams to coordinate with a couple different quilts, I used 3 coordinating tone on tone beiges. They turned out really elegant looking. From now on I am going to make shams using the fabrics in my quilts as I am making the quilt...then the shams will be all ready when I finish the quilt.
The directions for these particular shams were in a book. I will look up the title later on, if anyone would like it. I used fusible fleece to 'stiffen' the shams up a bit and help with the sections I used my twin-needle to quilt diagonal lines on. It took about 4 hours to make the first sham (including the time spent cutting out for both shams). I will try to post a picture later on. I think pillow shams are my new favorite thing to do!
