Not in my Pinterest

Yesterday I found out somebody posted some of my tangles on Pinterest, without mentioning where they downloaded the pics (my best guess is the private Facebook group Tangle All Around) or that I was the author.

This is pretty bothering and should be prevented.

I am wondering if I should start putting a kind of label with my name or the blog address on each of my drawings.

It sounds like the easiest thing to do. Or add a watermark. 

I wonder why people don't credit the authors.

I do my best here to list all patterns and authors, and I post mostly my drawings.

Here you can find the Pinterest board.
