In honor of our little girl’s upcoming birthday I’m going to show you how to get an invisible ink effect with Tombow’s new Fudenosuke Colors Brush Pens. I don’t know about you but when I was a kid I was obsessed with invisible ink, codes, and spy gadgets. I guess I never grew up because I still love those things! Recently, I discovered that you can use Fudenosuke Brush Pens under water-soluble ink (such as Dual Brush Pens) to create hidden text and drawings that can be revealed later. Here’s how!
Supplies:
Step 1: Create Your Hidden Layer
Use your Fudenosuke Colors Brush Pens to create your hidden text, drawing, or designs on the watercolor paper. This technique would be a fun way to write a letter to someone, create an invitation, a birthday card, a little note or a drawing.
Step 2: Create Your Top Layer
Let your first layer dry completely. Then use Dual Brush Pens in colors that match the Fudenosukes to cover the first layer. The Dual Brush Pen colors I found that matched well were: 856 for Red, 946 for Orange, 055 for Yellow, 195 for Green, 476 for Blue, 636 for Purple, 725 for Pink, 969 for Brown, N65 for Grey, and N15 for Black.
If you can still see the Fudenosuke ink through the first layer of Dual Brush Pen, let it dry completely and add a second layer.
Step 3: The Big Reveal
You’re finished, and you can send your creation off with instructions to wet each color with a paintbrush and water. Here’s what the rainbow invitation looked like after I wet each top layer color and the Fudenosuke ink emerged.
