Thanks everyone for the advice. I've already soaked in a hot tub this am and don't think I'll be doing any sewing today. Well, maybe some hand quilting in my lazyboy! I don't think it was from sitting to long....I have a puppy who needs to be watched like a hawk and has me up chasing after her every 10-15minutes, it's a wonder I get anything done. I have a Brookstone gel cushion stuck away somewhere from my days of 4-5 basketball games a week (my kids games, not mine) and it kept me from getting bleacher butt. Time to find that little baby and dig it out!
