Stitches used to execute this needlework picture are cross (over one and two threads of linen), counted satin, back, double running, and turkey work (a looped and cut technique as used for rug hooking, only on a much finer scale).
 
Marsha has been reproducing samplers longer than pretty much anyone.  I was lucky to tour her farmstead back in the 90s, and it continues to be a memorable day.  Her reproduction charts are thorough, and come with stitch diagrams.
