I put on about another eight to ten spikes last night while I watched tv (after I posted to the blog).
Today I wanted to keep going and then take photos of the inside and outside progress.
This photo is from last night just before I stopped working for the night.
This is the inside front -- the buttons.
This is the inside back -- the spikes.
This is the right-side-out back of the combo-creature.
Thirty-one spikes (so far)!
