Tangled Happy has a tutorial for a Granny Apron if you're inclined to make one.
My square pattern isn't the same as the one she has on the tutorial and I added the crocheted ruffle to the bottom by chaining three then single crocheting twice in each stitch. I think I'm going to add a doily pocket.
I'm also making a giant granny square as a blanket. Should have it finished by the end of the week. :)
