I purchased a wooden quilting frame which was set up for my machine and me. Back home just a case of putting it together. I was so excited and pumped up I did over two hours of nonstop quilting( only to fill bobbins). The next day I was over the moon with my success. The day after that I could handle move from my waist upwards. My arms, shoulders back etc all hurt. Movement was very difficult. I had done too much in one go.
Since then I have a 20 minute rule for any sewing. 20 mins sew 20 mins relax and catch up with jobs or have a drink. I have had no more problems.
