Concerning the part:
“As a Laurel, I know that this is not the way you do that one particular thing.”
I think the person who wrote this should better not have left the message and leaving the message she/he should have signed it – such people can destroy more than they can create…

… one of my major rules is – and I am no Laurel, just the head of a rather small kingdom level embroidery guild – if you criticize something, you should be sure that you know and tell what is wrong and tell the person how they can improve and always also point out the positive things about a work piece – just to criticize is easy, to help improve isn’t, but that’s what I expect from a Laurel and from other artisans…
…just my 5eurocents…
