These are from a place called Pincusion Boutique. She sells "Sweet Treats" made up of 8 coordinated fat quarters, and she offers lots of patters that use the sweet treats. Brilliant marketing! Here's her website:

This particular pattern is called "The Gathering." Look under the patterns (I think they're called "Pressed for Time Quiltworks), and you'll find it.
I've done several things from this company, and I'm always pleased with how they come out.
