I can pretty much crochet all day, the room where I work gets the south sun, so it's pretty bright all day. I do like to be alone when I crochet so as soon as my GD gets up I'm pretty much done until she leaves the house. Unfortunately my mom is in the hospital so crocheting time has been limited over the last week.
I more or less taught myself, but my mother was available to get me over the rough spots. When I first learned, joining a round was a real problem for me, I had many doilies that peaked in the middle. A little story about learning to crochet: I use to bite my fingernails really bad, my father would try to pay me to stop biting, nothing helped until I learned to crochet, my hands were so busy, before I knew it I had finger nails.
