The tip is....work on more than one project at a time using the same palate. It can be simply a matter of using up what's left, or really just taking a colour scheme and creating matching 'art'ickles (hehehe....see what I did there.)
I was creating a background canvas board and had put out too much paint... So out comes one of my journals and I started slapping on that paint. In the end I had two projects started ( in hardly any extra time) and I hadn't wasted and acrylic...you gotta love that!
The journal background made me think of underwater. Yes, I know there's no pink under the sea, but it's a mermaids prerogative to choose her own colour, dontcha know!
There's a lot of fluro colour on this page and it felt like an inner light, hence the journaling.
