ok Everyone has their own numbering system. We can ask Tom for his if he sees this thread.
John had been doing his work for awhile & I asked him about doing a particular cross & he said 'nope'. So you all know about the little red hen. So the little blond hen (at that time) did it herself. He kept track of his crosses by the year they were made, so I did the same thing. I started the same way but put a L in front of the numeral. John thought he might do J, but it didn't seem necessary so he went back to numeral first.
