thumb tacks for mask

I suddenly remembered that the Bahtinov mask didn't work if I had the dew shield on. There was no way to hang it. I stared at it for a few moments. Looked in the big fasteners parts bin. And got an idea. Tried some push pins with the Bahtinov mask. It worked! It's a quick fix, a little crude, but it does what it needs to do. I will need to be rather careful in the dark though...
