Mathmatical what?

It's bed time and I just remembered I didn't post yesterday either so I scurried down the hallway to take a quick pic.....and started counting non colored squares. Why you might ask. I wanted to know how close I was to being done with Witchy Wendy. It's 3,856 squares which turns into sometime like 15.8% left before I'm done. I've stitched 20,564 stitches so far. Woot! I asked my dh what I should work on next and he said the deer picture. It took me a moment to recall what he meant but I am now to tired to dig through floss to see how many of the 123 I'm going to need to purchase. I want to finish page one of the Fragile Heart SAL before I do a new start though.
