Also known as using leftover paint.
I add color mediums to waterproof surfaces often to allow me to pick up the color easily with paintbrushes. There is always color leftover when I’m done using it. So I spray extra water over the color and basically mop it up with a scrap of watercolor paper. I learned this a while ago from someone. And I’m glad I did. The results are always different and unique. I save these pieces to create other items out of, like punched or die-cut shapes. Often my scraps are small. But this time I found a couple of pieces large enough to be card front layers for some birthday party invitations I made. They gave a perfect dreamy background to go with the floating balloon card.
Make sure you use every last bit of color
