Thanks everyone!!!

I actually finally emailed Winkflash, and they said that it will actually print out fine. My 1st was blurry because I had only done it in 72dpi. They said that the one that I'm waiting to arrive will print perfectly. That it was just an issue with their preview screen that was making it look so horrible. So will see. I was amazed though, I got a response within an hour of emailing them, so thumbs up for Winkflash!!!

I do do all my LOs in the final size.

Again, thanks!!
