Because the blocks are big it would make a cute and quick winter throw. Just need some coordinating fabric for extra blocks. If you don't want to go that route you could make some quick two sided pillows.
That being said you could still do pillow cases but you may need to add a little fabric to get it to the right size. Those border snowmen would look adorable as the edge of the case.
It's really cute fabric, be sure to share what you do!
