Puzzle Piece

I am doing Jean Hilton's Puzzle Purse with the ANG Cyberpointers group.  I did not want to do a purse, so redesigned the outlines and I finally got them all stitched.  The pattern calls for #8 Pearl for the outside square and #5 Pearl for all the rest.  I found the #5 to be much too heavy and did all of it in the #8.
I think the Bargello comes next.  That will go in the large diamond and I'm thinking about setting some stones in there first.  I have a bunch of turquoise/aqua stones I have been collecting, so will see if any of them will work here.
