This is nearly all of my SoulCollage deck with the backs finished. Some are a little sticky still, but nothing that can't be managed. Little tidbits were added to a few ~ feathers, pressed flowers, confetti. I used an old credit card to spread the acrylic paint around, waited for that to dry and then covered the lot with matte medium finish. I feel rather nifty.
And it's true, patience isn't my strongest virtue when it comes to finishing a project. I didn't have another ball of the #147, but I did have the same Vanna's Choice in #304 Seaspray Mist. Like Steven Wright, I match my socks by thickness.
