The last project I started at this past ASG retreat, was The Last Supper by Anita Goodesign.  I am doing the appliqué and embroidery version.  (There is also a printed-fabric version).   I didn't finish this project, of course, but I did get several blocks completed.

My work in progress.

There is so much embroidery in each block.  I am doing block size "C", which fits in a 6"x6" hoop.  Each block has about 30K to 45K stitches.  The appliqué is used primarily for support in much of the design, as there is so much embroidery on top, you may not even see or recognize the appliqué fabric underneath.

Progress and finished detail of one block. You cannot even see the pattern of the grey appliqué fabric under the embroidery.

Progress of another block from appliqué to embroidery on top.

Late night stitching at the retreat.  Just a few stitchers still hard at work.
