I was asked about this technique a couple of days ago, so this is for the people who are still unsure how to do it.
Please forgive the rushed colouring job.
Position your cutting die over your image, framing the area you would like inside the frame.
Draw a fient pencil line around the OUTSIDE edge of the die
(i used dark pen so you can see it in pics)
Cut around the parts that are outside the circle, cut further into the image though-if you follow the lines of the image it wont show up later, for example, I have cut up her arms and both legs, this is so i can slot the die in place easier-you will understand when you do it yourself.
This pic is to show how far I have 'cut into' the image.
Slide the image into the die with the 'over the edge bits' above the cutting ridge. Jiggle your die around to the correct position- I moved mine above my line because i decided it was too far away from the little girls botty. When making your final adjustments for where you want the die to cut remember the cutting ridge is a couple of millimetres in from the edges of the die.
Now trim your excess bits off.
Now I need to turn her into a card or something!
Hope this is helpful.
