Thank you, Thank you, Thank you!! That website also sells the blue fabric. I used that description on Google and the fabric is called:
"Fairy Princess" by Leeré Aldrich for Clothworks.
If anyone is interested, the link below also includes a free quilt pattern using this fabric (which saves me a lot of trouble in creating a new one for my sister!).
