Hello,
I would like to submit entry's but what exactly the size of it? Is it confirmed 8.5x11! Because given template is of 11x6in.
And is it more Flyer oriented? or Post Card should be designed two sided and spacing of address(postage) etc?
Thank you.

Approx. 8 x 11. Just 1 sided, it's a flyer, not a postcard.

Thanks,
John
