@Terrificli -- what is fascinating (sad?) is how useful a thimble is when one gets older. I've been known to sew on a stray button here and there and never had to use a thimble when I was younger. I sure need one now.
Why? My eyes aren't as good as they once were and a thimble has saved me from jabbing my thumb with a needle on more than one occasion.
So, let me add to your statement -- go for a metal thimble because you need something sturdy to protect you from the mistakes that come with poor eyesight. Those plastic ones aren't worth a penny.
