I started simple and those are the cards I'm posting... the only thing I would say, is if you are going to try this... lay the white on quite thickly - especially with pastel backgrounds. As you can see some of mine are quite faint.
So simple but effective! Keep scrolling for the video tutorial!
I am so in love with this technique and will be sharing a REALLY special card tomorrow!
And here's the video - I hope you enjoy it and will try this yourself!
