While looking on Pinterest, I find cool bath bomb recipes, body scrub recipes, etc. They all had something in common, they required some kind of dye. Either soap dye or food coloring. I didn't have any of that, and so I thought of what I could use instead. I came up with the idea of cutting open a marker and using the ink out of that! And it worked:)
Of course some might be like: isn't that bad for you, you know all those chemicals? Well guess what, I happened to have non-toxic markers so I figured it was perfect!
The picture is of a scrub I colored with this technique. Check out my posts for the recipe to the scrub, I have multiple you can try ;)
