Hi Kevin,
#87 and
#88 are both two colour options.
#88 uses a PMS colour and a tone of the same colour, allowing it to be economically printed using two inks... this of course is no help for embroidery, which is why I have suggested
#87 as a two colour option without the use of a tone.
#89 is obviously greyscale, printable using black only.
#90 and
#91 are options for single colour or black. Of course these could be translated into any single colour.
Cheers,
Robin.
