How do you decide what you want to do? We like to play with kids sidewalk chalk. Get a big stick of White or blue chalk and start drawing. Kid chalk works great and it is only about a dollar investment. Do you want a border? Do you want a tile pattern? Draw it out. Do you want a river running through it? See how it would look. Don’t like it? Hose it off and start again. Have fun and let your imagination run wild. Concrete is fun. Don’t restrict yourself. Look on the internet and see what other people are doing. Take one part of that idea and add something of your own. Take one part of an idea from a plate and another part from a pillow. You get it, now go do it!
