No.

I know that I'm slower than many - I also know that I'm more fussy/particular than many.

No I don't. When I retired I took off my watch (after 35 yrs of teaching) and don't count the hours of my lovely lovely hobby.

I've tried a few times, but just end up getting too busy & too much trouble. I do log the dates I start & finish on a spreadsheet along with pertinent info ie: fabrics, patterns, type of batting, sizes (before & after quilting/laundering) & photos of each.

No, but when you get your machine serviced most machines have a stitch counter/timer. You could ask your serviceman about it.

I make quilts for my nieces and nephews when they get married or have a baby. Since some of them have no idea what a gift of love that is (although most do) I have kept up with it at times and told them. It always gets a "WOW"!

No. We have a word for that kind of thinking around here.
My son just got out of 6 yrs in the Navy, he was in the nuclear propulsion dept of the USS Ronald Reagan. Ever since they sent him to school to learn what he had to learn, we noticed most of these sailors are very left brained, and over think things to excess. We now are calling it what I would call that kind of thinking as related to quilting:

NUKING IT!

When I make a quilt for a customer, I record all my start and stop times. Then I usually round it down. I also do the same thing if I am sewing for someone, like making curtins etc. I really try to be just with myselft and my customer.

I used to keep the number of hours...but then I kept making more and wondered what was the point...I'm going to finish it regardless of the number accumulated...lol

I don't think I could keep track as I stop and start too much. You know, stop to throw in a load of laundry, stop to answer the phone, stop to fold a load of laundry. Feel guiltly and stop to clean a room, sweep the floors, you know how it goes.

No but keep saying I will - Thanks for reminding me. I actually have one that I need to start and will be cutting this evening - maybe this will be the time I do! Then again maybe I will get so far along and then forget. Honestly I really do want to do this so thanks for bringing it up at just the right time.
