I'm fortunate to have a quilting machine on a 12 foot frame but still standing for long periods of time can become stressful on the poor old body especially the feet. I have one of those rubber mats that looks like a jigsaw puzzle along the front of the frame and that does help. I'm also drinking lots of fluids and munching on fresh veggies, at least this week. That means lots of trips to the bathroom with all the fluid intake so I do get some breaks. Plus I have my main computer down here also so I'll check my emails from time to time plus I keep my Ipod singing away also.
