Thank you for letting me know about it being on Pinterest! I had no idea. I guess if it's out there like that now there's really no point in having you take it down from your blog--credit is really all I'm looking for.
I will happily credit you, right now in fact. And link back. And yeah, I know how you feel - I’m a photographer and see my stuff hither and yon online with no credit.
Nice work, btw - very well done and absolutely brilliant!
