I LOVE DOODLES.
I like to use them as if they are stamps or paint in the background, or place them on a page anywhere I can imagine I would draw or write something. They are great for creating your own project life cards or adding a handmade touch to your pages. They look the best layered on top of flat paper shapes (use a clipping mask to make it look like the drawing was drawn on the paper before it was cut), or on top of a photo (pretend it's a photo pen or opaque marker), or in the background of the layout mixed in with painty stuff. NOT on top of flowers... anywhere you could draw with a pen in real life.You can also enlarge them and clip papers to them and add a drop shadow to make it look like it was a paper shape cut from a silhouette or something like that.
I also like to make the doodles into elements. You can color in the outlines by making a layer underneath and filling with the paint bucket tool or a brush. Then, flatten the layers together and then add a white stroke (about 13 pt) to the outside of entire thing to make it a 'sticker'.
Like Zakirah said, you can add styles to the lines themselves, turning them into 'wire' or 'plastic' shapes, or glittered... watercolor, chalk... the options are endless. I also like to play with layer styles and use settings like lighten, color burn, multiply, overlay, etc. to make them more interesting over photos or patterned papers.![]()
