Dear Gayle,
   Yes, I believe they are small tissues.  The
workshop went over IHC for dx of lymphomas.
I will be doing equine hoof so will do Diane's
method.
   Another question, is the infiltration steps done
at room temperature?  Is the infiltration and
embedding mixtures stored at room temp?
thanks for your reply,  Sarah

Gayle asked:
I presume Peter Jackson's tissues are relatively small?  Are they soft
tissues?  I am curious about the size of block he uses?
