Well I have FINALLY got to piecing on my 12000. Had it since mid Dec. Not done a thing - Yep that right mid Dec. oh except 2 hours with dealer on setting up embroidery. In the mean time it has been looming threateningly at me - when I was home.(have been away a couple of times). Today I piced a small quilt - simple squares which I may send to A linus quilt coordinator. I noticed while stitching using 1/4 inch foot O and P2 stitch that as I paused to adjust pieces then restarted there was a movement in the bobincase area. Foot of course was down so I figured it must be to do with the foot up down program. I found it strange to not have to manually raise the presser foot!! Guess I will get used to it. I previously had a 6600 and for 6/12 the 7700 (before trading for the 12000. Looking forward to exploring more now I have bitten the bullet
