Hi Crystal,
Welcome to the group. It's good to have another join us. I have been AWOL for awhile, but I noticed your question about mirror image.
Actually all the patterns need to be printed on mirror image. The symmetrical ones won't matter, but the ones that aren't need to be printed mirror image. To be on the safe side I set my printer to print them all mirror image after I discovered this when I did Captain's Wheel.
So long answer to a short question, but if you print them all mirror image then you'll be okay. Hope this helps.
