Even though you can't see the detail, I splattered gold paint (Peerless) to fill in the background. I also used a Quickie Glue Pen (Tombow) and added glitter to the flower stamens and a little white Uni-ball Gel Pen. Happy Birthday sentiment (Stampendous) was colored using Gelato directly on the edge and blending with a brush. Ribbon and gems (A Muse Studio).
Here are the Gelato colors I used for the card. If you aren't familiar with Gelatos, there are numerous YouTube tutorials to help you through all the techniques!
I'd say my favorite wet technique is water coloring as in my card today and my favorite dry technique is to Gesso cardstock, scribble on color over the dried Gesso and blend color with a baby wipe. Perhaps next month, I'll work with that technque!
