I spent a couple hours this afternoon trying to start a fire with a cheap magnifying glass. If I had a decent tinder bundle I would have succeeded. Amazing how easy it is to get something smoking. Burnt a whole bunch of stuff, just never managed to get to fire.
We have some Lamb's Ear [1] in our garden that I had a decent amount of success with, but I used up most of the dead stuff from last year over the course of the afternoon.
