Testing for fiber content
I usually do a burn test on fabrics that i have acquired that are " unlabeled."
I did not do that with this piece and put a hot, dry iron down on it in the middle of the piece. That did not work out well.
Lessons relearned:
Check for fiber content - do not assume
A certain setting on one iron may be a different temperature than the "same" setting on another iron
It seems that a fabric will tolerate a higher temperature if moisture is present than not. Pay attention to the water level in a steam iron if using steam so thAt it does not go dry.
