You will need: Something to cover your work surface with, especially if it is your best dining room table and some smooth or glossy cardstock. In addition you will also need some reinkers. I tried distress inks, but it didn't work. These inks are a very old set I have by Ranger called Posh impressions inkabilities. I have no idea if they still manufacture these I am afraid! You will also need a knife or something to scrape the foam off with, a can of shaving foam not gel and old lid or plate and maybe some gloves if you don't like getting ink on your fingers! Gather all your things together and get ready to play!
Next take your knife or any thing else you have to hand and cut across the surface of the shaving foam. You can experiment a bit if you so wish! I wouldn't play around with it too much though as the colours will start to muddy and you won't get such a pretty effect.
When you are happy with your swirly pattern, place your cardstock on top of this and take a print. You can repeat this several times if you wish.
Next peel it away from the foam and scrape the excess foam off of the surface of your cardstock. Wipe the scraped off foam in some kitchen towel.
