Firstly, stick ripped pieces of text, sheet music, paper doyleys etc onto an A4 sheet of paper. Add the collage pieces randomly, overlapping the edges. Allow to dry then cover with a wash of paint, blending a few colours together. I used a 'Pearlex Pallette'.
Add some stamped images in co-ordinating colours, again in a random fashion.
You can then decide which areas of the sheet you want to use. The photo below shows the left over sheets from the 'chippies'. These make ideal templates to draw around, then cut out. At only 99p they are a 'bloody bargain' if ever I saw one!!!!!! (oops sorry, I have to spoil it, lol)
Seriously though they are A4 size and real nice quality chipboard shapes. The templates can be used over and over again.
You can also make templates free hand like the heart above, then move it around on the sheet until you are happy with what you see inside the template. Then simply draw inside it and cut out. Cut as many shapes as you need. Another way of using the sheet is by simply cutting it into squares of a set size, then jumbling them all up and rearranging them on a contrating background.
