You need to find a realistic print of animals, flowers, people doing action movements (athletic moves) and preferably not have a solid color background. For example : you'd want swirling wavy water with ducks on the lake, soccer players running dribbling the ball, parrots and tropical birds on green leafy background. Find your length of the repeat, buy 6 repeats (if making hexagons). Depending on how long the repeat is, will determine how much fabric to buy. If the repeat is 12" or less you probably want 12 repeats, but if it's 18" or longer than 6 repeats should be enough, unless you're making a bed- size quilt, then you'd need more. The folks at the fabric shop can help you buy the amount you need.
