First, I'd added my hst patch last year, but because I am an idiot. I put it where the strap would cover it. I corrected that today:

Next, I've become somewhat obsessed with cutting pack weight, and one thing I did was get a "luci" solar light. It solar charges, weighs 3.6oz, and provides loads of light for hours, and in a somewhat diffuse way - nice around camp.
Anyway... I used some 3m vhb tape to adhere a couple strips of Velcro to the lantern, then sewed the matching strips to the top of my backpack. Throw in a piece of cord and a little carabinier as insurance and for hanging in camp.
