I talked about this a few weeks ago. Not having the right color brad. And, the Sharpie just did not quite match up the way you wanted it to. Here are two other ideas you can try. So, 2 tips for today!
Have an embossing powder the color you need? Dip or touch your brad in VersaMark first, then into the color embossing powder you want to change the color of your brad to. Carefully hold the brad with a pair of pliers and heat set it. Done. New colored brad!
You can do the same with Stampin’ Glitter. Poke your brad through a scrap of styrofoam. Use Tombow glue and ‘paint’ the brad and either dip or sprinkle with the glitter a few times to completely coat. Let dry. Wow, your very own glittered brads!
