I finally found the matching shams on Wayfair. They are not linked in any way to this quilt on the Wayfair website, but they look to me like they are an exact match.  This picture was taken before ordering the shams. 

Shams are listed on Wayfair as Guiliaine Pillow Sham.  Other items purchased from Wayfair include jersey sheet and pillowcases sets, waffle weave blankets, knit throw blankets, floral throw pillows and dragonfly floor lamp.  Pleased with the overall look.
