Measuring

David came to visit for a few hours this afternoon and he was telling me how much he’s been learning in the glass studio. Lately he’s been cutting metal, building kilns and suggesting changes to the software they use to control the heat.
Something that’s made a big impression on him is just how much the little things count. For example, when you’re cutting metal you lose about 1/16” with every cut you make, so that has to be factored into the figures when you’re ordering supplies.
This reminded me of that old saying: measure twice, cut once. I'm sure we’ve all learned this the hard way at some point or another.
