YAY! Pictures!
I like the navy much better than white.
And I like the blocks made out of the WV block fabric.
The mix of the 3 different blocks is fabulous. You could make some 4 patches with the white print and navy fabric, or some with the navy and yellow.
But it's fine if you just keep the 3 you have already. It's just perfect for a college kid.
Your nephew is going to love it!
