I’ve been legally blind (correctable) since I was six years old. My grandfather taught me to melt crayons with a magnifying glass, and I went about melting and making castles a la Disney. When I went to school the next year the nurse slapped and scolded me saying that no one could possibly loose sight as rapidly as I did (three months), thumping my head she said “Now read that chart!” which of course I could not possibly do. With burnt out corneas I was put in bifocals early on, and have been in thick specks ever since.
So lessons then and lessons now, I think for the first attempts they’ve turned out rather well. At least the color scheme is nice and 'some' of the points worked out well.
One thing I did note. The suggestion to halt the machine and hand crank does work. True, I failed to get all things even, if nothing else each attempt spurs on knowledge and incentive. What I wouldn’t give to have Granny or Grandmother here for a lesson or two…
