How Many Hours a Day do I Crochet?

It varies. Since I don't have a job, you'd think I have 8 hours a day to crochet. Well, no. There's house work and yard work and gardening and reading.....
4 to 7 hours is closer to how much time I have for crocheting. Sometimes less, rarely more as I do get bored. My daughter says I have project ADD. I have trouble saying how long it takes to make any one thing because I don't work on any ONE project non-stop.
Plarn projects take a little bit more time since I have to cut the bags and fasten the loops together before I can crochet. Obviously, scrubbies are faster to make than shoulder bags, which are faster to make than grocery bags.

I've found that the coasters to the Pineapple Parfait set are slow going since I'm using a size 3 hook instead of a 00 hook. I can't crochet as quickly with the smaller hook. They are smaller than most doilies I make, so they can still be made in fewer hours-about 6.
I can crochet really fast with yarn and a size I or J hook, but afghans need so many stitches to make that they take weeks or months to make.

How much I crochet in any given time frame is relatively easy to answer in term of hours, but has too many variables (size of yarn and hook, size of project) to be answerable in terms of projects finished.
