The technique in question is the use of magnets on my card. And not just to make an actual magnet, but to make a paper doll :) I use to love playing with my Princess Diana paper doll back in the day, the kit came out with a ton of dresses for the deceased princess and I think I remember changing the clothes around so much that I wore off the tabs that actually held the clothes in place! hahaha!
The paper doll I made was compliments of Mo's Digital Pencil, Images I used in particular were a freebie set called Trudy's dress. A set downloaded long ago, so I cannot even tell you where to find it for your yourself unless you go hunting on Mo's site (that's Mo Manning for those who don't know).
The pictures tell the story, I stuck a strip of magnetic tape to the back of Trudy's party dress, as well as to the back of Trudy's image. I made sure the two strips aligned before I adhered, I also made sure that the magnetic sides facing each other were opposites (very important, else the dress will not 'stick').
The entire Image was coloured with a mixture of watercolour artist's pencils and plain colour pencils. All paper came our of my scrap heap, as did the very short piece of ribbon for Trudy's dress bow (see! hoarding helps!)
The card went to my friend Rachel, see how I cleverly inserted her name on the gift tag behind Trudy? Clever me! LOL!
