Is grain direction information available somewhere online? If not, what is the grain direction of the Lettra 300 gsm, in all of the available sizes? Also interested in knowing the grain direction on Strathmore Pure Cotton 300 gsm sheets, all sizes. Thank you!

Grain direction is normally indicated in the paper format. For example, in a 22x30 sheet of paper the grain direction will be indicated with the second number - or the length of the sheet. In this case, a 22x30 sheet will be grain long. If this same sheet were Grain short, the listing would be 30x22 (or 30" wide by 22" long)
