Quilt Blogs are valid, especially the ones that are blogs from the fabric industry or magazines. Bloggers have too much invested in their blogs and reputations to gyp someone. Especially the designers and shop owner blogs. You never have to give out more then an email address and if you win then you are contacted through email. You can have the prize sent to any address you want under any name you want. I always post a thank you on the blog if I win.
