I was knitting at night while watching TV and determined it took me about 2 hours to knit a square. I realized this when I started a square at the beginning of NCIS, and finished it at the end of NCIS LA!!! One side border took over 3 hours (Harry Potter and the Deathly Hallows - Part 1).
One dreary, cold Saturday, I decided to use up some stash yarn and do the CAL, too. I watched a marathon of Psyche (Gus cracks me up) and by the time the all day marathon was over, I had 80% of the CAL complete. Of course I didn't sit and continuously crochet during the whole 8 hours, but the CAL clues went really quick, the larger clues about 30 minutes each, the smaller ones were cranked out in about 15 minutes!
