I find that signs101 is a usefull place in that a lot of the people here have an eye for fonts and clipart and such. I'm amazed at the time it takes for replies, that's why I posted it here. I always try to post here last, after doing my own research.
I prefer Fred's sites first, then clipart.com, then Microsoft Office clipart pages, then Google search, and if nothing turns up, post to signs101 and see if anyone knows.
I've read enough newbie posts and the thrashings that follow to do a little research prior to asking.
And doug, I'm pretty sure I've seen that one somewhere; then again I've only looked at about 14,328 clipart images of welders today.
