Hi TDP,
This could be a paper not related to either of those papers. Does the supplier list who the mfg is?
Toying around with the idea it could be one of the papers you named, and another name for it... then my guesses would be something like this:
*If* I had to take a guess if the paper would be Ironall or Alpha Gold by another name, of the two papers, I would pick Ironall because of the "flex" in the name. Ironall's top quality/feature is the stretchy flexy quality it has.
This name isn't on the original list of "other Ironall names" but that does not mean the paper isn't Ironall (or Alpha Gold) because anytime a supplier decides to add Ironall (or any other paper) to their line up, they can invent a brand new name for it. On our side, if this is a new name for, well, the Ironall is the one I am keeping a list on, then we can add it to the Ironall other name list if it turns out to be Ironall.
If you find out for sure if this paper is another Ironall paper, will you post a note in this thread? Thanks so much.
IRONALL LIGHT other Alternative Names and Suppliers
One thing that can be done is to order a sample supply if you want to try it.. if it's the aquablue back, and stretches with the shirt, that is a pretty good clue it's Ironall.
