You could just make a few baby squares here and there with leftover yarn bits and keep them in a box somewhere to be scarfed later.

Made some progress on my blankey today! I think I was able to finish 5-6 squares? Would count but DH is home and it's very shhhhhh! I'm hoping this will be a Big Awesome surprise.
Also, some of my Red Heart yarn is kind of stinky. Just smells like ugh, straight out of the ball. Has anyone had that happen before? Any tips? Heck, I don't even know if you can wash this stuff. (Can you tell I haven't kept much of what I've made? lol.)
