Black & White Stash builders

Here's two finds for my black and white stash.  These were on clearance at Walmart today for $1.50/yd.  Guess you can't beat that for a beginner quilter.  I'll be using them in the Supernova Quilt Along.  I think I have dedided to use some of my huge stash and red and whites.  My Supernova Quilt Along quilt will be made up of reds and white prints, black and white prints, white backround, and just a little yellow to make it POP! ...and that is my final answer.
