So I thought I would post it here so others might find it useful.
Please note I am using DS to make this card.
To make the card itself I used the shadow key and the Donald & Daisy image
I flipped one image so they faced each other, and nudged them together.
Once they had joined up enough I previewed it to check and then could cut it.
For the white inside I used the same image but just clicked on the Shift Lock instead of the shadow and so you get the outline only but at the regular size not the shadow size.
Then did the pieces for the front as normal.
I hope that makes sense - feel free to ask any questions if I missed a step or anything.
