First off though, here's my card.
I've masked Tilda Makes A Blueberry Blanket onto Old Swedish Chair and then coloured the image in with Distress Markers. The papers are from Maja Design, I've distressed the edges with a Tim Holtz distress tool, and then machine sewn the edges with top stitch thread. The pearl brads, seam binding and lace are all from The Ribbon Girl.
Here's the masking tutorial,
Stamp your character image onto a post it note making sure you get as much of the image onto the sticky area as possible.
Carefully cut out the image using sharp scissors, keeping as close to the image as possible.
I then mark this on the back of the stamp, so when it's mounted on the acrylic block I know where I'm placing it.
Stamp Tilda onto the paper you are going to colour, and then place the post it 'Mask' over your image (you'd be shocked at how many times I have actually forgotten to do this, lol).
And then stamp your accessory image.
Ta da!! Tilda sitting on a chair.
Give it a go, but don't get disheartened if it doesn't line up, like everything practice makes (ahem) perfect.
