Not enough room to journal because there is 'something else' in the space you need? Sometimes what I do is use my journaling to accent a sticker or die cut.

For example, in one 'crazy hair' picture of my son, I used a Stickopotamus blow dryer sticker. I made my journaling, which was something to the effect of "Check out that crazy hair do!", look like a cord coming off of the hair dryer. It turned out really cute!

You could also journal for the strings on balloons or a kite, or the water coming out of a whale's spout.
