All you do is apply inks to the block- you can use markers as well as inkpads.
I used Distress Inkpads- Mustard Seed, Wild Honey, Salty Ocean & Peacock Feathers.
Then spritz with water. How much you spritz is up to you, and the surface you are going to stamp on, I found. The watercolour paper takes up a lot of the water, so the result can be patchy if you haven't added enough.
On the other hand, on smooth card, you want less water. And you don't want that much water that the ink runs when you start to flip the block over to print.
First print, not too bad- you can spread the ink a little with a fingertip if its blotchy.
I topped up the ink, and added a lot more water this time.
Excess ink in the corner, from how much water I added. I soaked it up with a piece of kitchen roll.
Went a bit mad experimenting, and made a few more. I decided to trim them all down, and use as backgrounds that way. Not sure how successful this would be using it straight onto your card front- I think theres too much likelihood of the card warping as it dries.
