If you "squeeze" the lid and base together of a Stampin Up ink pad it gives you a little pool of ink which you can use with an aqua painter brush. I didn't have an ink pad for the blue only a marker, so I scribbled on an acrylic block to get some ink and then picked it up using the aqua painter.
Hope your weekend's going well. Off to see my folks who have just moved home!
