There was a saw involved, but it was the sawdust wot did it.
So, I've got ear defenders on, mask and safety goggles and I'm outside cutting lath with the wind blowing away from me. Table saw hits a knot, piece flies up, bounces off cheek and under the tiny gap in glasses and embeds itself in my eye. OUCH!!
Doctor said its not there anymore, but It hurts a lot.
At least I've got the ceiling lath finished and I was going to put the scratch coat on today, so that it's all plastered before I go digging at mums. That won't happen now, as I can hardly see out of it.
