Here I did a collage with 3 stamps - bamboo, buterfly and fabric background (its quite subtle so doesn't show up very well in photo). The background lines you can see is scored with a Scor Pal. You score the lines one way then turn the card and do the same the other way to get the criss cross effect.
Stamping is done after the card has been scored. If you haven't seen a Scor Pal, here's the link http://www.scor-pal.com/
I find it very useful for all sorts of projects. Hope you like this card. Size 13.5 x 13.5cm
