Isaac and Dad, spread

OK sister spill me your awesome ways - I can't get my 2 page layouts to look like this in the gallery. Would you mind telling me what size you do?

@KittyY Yep, it's really too easy! Create a 600x600 blank white file, 72dpi. Crop your full spread to be 600px wide, 72dpi. Then drag and drop the cropped spread onto the blank canvas. So there is actually a blank white strip above and below the photo, but it doesn't show up... so it makes the page fit the square preview format in the gallery.

You my dear are one big container of Awesome Sauce! Thank you!

Love this!! Perfect combination of colors and pictures,
