Sometimes I like to make a reverse shape with punches to get a #D effect on my pages. So instead of building up a 3D effect with layering I dig it down into the page. It can be done with ordinary punches or "anywhere in the page" punches.
It can also be made on tags - easier to handle in a cuttlebug or similar.
Behind the hole you can choose any pattern paper or confetti or a transparency depending on what effect you would like.
Some inspiration for you:
This is a detail from the May inspiration page - so I wont show the whole page just yet ;)
Here I used the technique on a tag and used different pattern papers between the letters in "pretty"
If you decide to try this I would love to see what you have made so please make a link as a comment to this blog post
Have a great scrappy day!
