The recommended ink pad for stamping images that you intend to colour with Blendabilities is the Memento Tuxedo Black ink pad but isn't it nice to know that you can use other ink colours. I haven't tried it yet - but I will be. The main thing to keep in mind is that you must be sure your stamped image has dried before colouring with the Blendabilities.
For those of you unfamiliar with Blendabilities, these are Stampin' Up's line of alcohol markers. They come in sets of three and take your colouring to a whole new level simply because they blend together so nicely. Take a look at them here.
