Lisa Gentry broke the Guinness World Record for the "Fastest Crocheter" on June 25, 2005 at a Michaels Craft store in Monroe, LA. She crocheted 853 trc = 5113 stitches in just 30 minutes which = 170 sts/min.
Just for fun I thought that I would give it a try...well...it seems that speed crocheting is not my calling. My personal best was 12 trc.
I would love to hear how others made out!
