Take one paper doily and four butterflies...
This technique is very easy but looks really effective.
In the card above I have masked using a paper doily and some punched butterflies.
When you peel it off you may need to rub the glue off with an eraser.
Next punch out 3 or 4 butterflies and lightly stick them to your cardstock.
Sponge again in different colours.
I have chosen to leave the butterflies in place at the top and bottom - just lifting their wings of the page.
