Rattie Fursuit Feet : Part 1

This weekend we worked on our rattie fursuit's feet.  My 14-year-old provided a pair of comfy (I would have preferred new) runners as a base, and we built the feet around them with foam.  We have yet to finalize the trimming/shaping, and then need to cover them over with the pink fleece.  Here are a few photos of this weekend's progress :

I've got to do something about my glue gun.  I have a large gun which doesn't work well (although I forgot what the issue is), and a small gun which works well, but the trigger is really hard to push.  So even half an hour after finishing with the gluing, my fingers are still red and sore.  Last time, when we were working on a paw, my fingertips were numb for a couple of days afterward.  That's not good, since we have lots more gluing remaining - when we create the head.
