Catching fire building birdhouses!

I wake up early often with a new idea design on a birdhouse.  I stumble to the garage and turn on my propane heater and then return in a few moments in robe and sweatpants before showering to put it together before the thought flees.  This morning, I smell smoke, look around, finally look down and see it's my robe!  I was lucky to be able to rip it off before it went through my pants for major burns.

I think I've learned a lesson about safety when working with major tools and heat.  BE AWAKE AND ALERT!
