I do have a clock in the sunroom where I sew, but I can't see it from my sewing table. I have either the radio or tv on most of the time, so that gives me some idea of the time, plus I always have my Blackberry with me That has a clock on the face. If I have limited sewing time, like in the mornings before work, I set the timer on my Blackberry. It plays Fur Elise when my time is up.
