Here is a simple idea @Former-Member. Paint a background page any colours you like. Work in stripes across or up and down the page, mixing a couple of colours with white, not being too fussy about the neatness of it because it all adds character. Then draw other images ..... here is an example .... on another piece of paper (copy something someone else has drawn, and don’t mind if it’s not perfect or doesn’t look a lot like theirs ..... it will still come up beautiful in the journaling style. 
Cut them out and glue them on your painted page, then draw a line around the edge of each pasted on piece with a texta in another colour. Let it all dry (you can use a hairdryer to help it along if you’ve got one) ......
Then write solething on it with a black (or other colour if you like) texta, and draw a box around each word or phrase, like this .....
Then draw a border all around the page to frame your work ...... colouring it in with textas if you like .....

Sign the bottom corner somewhere.
When it’s all completely dry, go over the whole surface with a glue stick or PVA glue to protect the work, and let that dry.
