Reply To: Letter Symbols before pattern sizes

[the_professors_assistantKeymaster]

I don’t know if there’s a master list as these are codes created by the pattern companies and aren’t necessarily universal. From what I’ve noticed the codes represent size groupings so maybe B5 in McCall’s is always misses size grouping 8-10-12-14-16. Each code (or size grouping) will be in one envelope so there will be an envelope with sizes CL (6-7-8) and then another envelope with sizes under the F5 group. Of course, not all patterns come in all size groupings and I guess it would depend on how big the patterns are and how many sizes they want to fit in a pattern that determines what pattern groupings they use. I hope this helps a little.
