I peice the quilts on machine and hand quilt them...When in my recliner I am ok it is the sewing machine work that kills me...right through by shoulder blades and up my neck....i just can't explain the pain...it is like someone is pinching my spine and cracking my bones....it gets better with time...takes about 2 weeks before I can sew again...My chair is a good one and my table is the right height...guess it is just all the sewing when younger and computer job I had been doing for last 2 1/2 years...I am going to give myself some time off and see....The thing is I am all by myself during the week and as of June I have no job..Sewin gives me something to do...But like I said I am goin to stop for awhile and see...then start back slow...
