Although it has been reported to me that a laundering fixes the issue, I have always gotten terrible marks from the heat platen when forced to press rayon and rayon blends.
About a year ago, someone posted that the Stahls Rubber Protector sheet was the solution. I assume that that is the "Flexible Application Pad" marketed to protect buttons and zippers. Is that truly the case?
Is there a set number to adjust temp top compensate for the additional "insulation"?
