Here's a clean and simple card using masking and colouring.
I took a scrap piece of paper and used a circle die to cut a circle from the centre. I used re-positionable adhesive around the edge of the circle to make a stencil that wouldn't slip about. I place this on an A6 white card where I wanted my image to be.
I stamped the Cow image from the Lawn Fawn Hey There Stamp Set and the little cake from the Lawn Fawn Beam Me Up Stamp Set inside the circle and coloured them with Copic markers.
I then used more Copic markers to colour the grass and the sky around them.
If you wanted you could use distress ink or oxides and mask the images or use the co-ordingating dies to cut the images out and pop them on top.
I removed the circle mask and stamped the sentiment Happy Birthday To Moo also from the Hay There Stamp Set from Lawn Fawn.
I hope you like it.
