I love all the cute clip art that I see everyone using on all the great blogs and Teachers Pay Teachers items etc. I'd love to create some things that I can share on my blog (and maybe eventually on TPT) but I don't know which clip art sets I can do that with. I'm paranoid of posting something using someone's clip art and then getting in trouble!
So, if you use clip art for games, documents, blogs, TPT, etc... which ones are the best, and okay to use!?
