I did a little experiment today. I had an old dried up manicure correction pen from a long time ago. It came with extra nibs that I had never used.
And I thought it might be interesting to make a blender out of it.
So I took out the plastic covered little sponge and washed it several times with (dish liquid) soapy water until I couldn’t smell the acetone in it anymore.
Then I left it to dry out completely.
I was going to fill it with Glycerin, but at the last moment, I thought of something else.
Usually when you blend with baby oil on a drawing you use a paper stump, and you sand it off or switch as you change colors.
I wondered if it would work if I filled the pen with baby oil and made my own color pencil blending tool.
So I set the little sponge in a small dish and left it to wick up the baby oil. Did the same thing with the pen (new nib inserted.)
I’m going to give it a good try out soon, but testing so far it seems to work quiet well.
So there is an idea for your own, baby oil blending tool.
