But I have a magical pen

I was trying to write in my beautiful BOS using my old goose quill pen and dragon's blood ink (the latter of which was purchased). The paper in my BOS is a fine home-made quality type that, unfortunately, was soaking up the ink faster than my quill could write it. Consequently, I ended up with splotches instead of words.
Determined, I took a few of my gel ink pens (I have many of them) and decided on a Uniball, something that has a large ink reservoir and is easy to disassemble with pliers. Into a container the black ink goes, and I washed it out with water.
It took some practice, but I can finally tell you the secret to filling an ink pen with your favourite magical ink. Use a long, thin stick!! (I used a sliver of an incense stick, about 5" long, .7mm diametre) to guide the ink down. Otherwise, you'll end up like me: Red, smelling of dragon's blood, and wondering how exactly you'll explain your current state to your husband. (Thankfully, he's used to it. After painting my drum with empowered paint, I came into the bedroom (where he was napping) naked and painted head to toe with black spirals, splotches, and power symbols. I think, after he picked his jaw up off the floor, that this is when he stopped being surprised at my antics!) )
Seal with a bit of beeswax, and you've got yourself a functional pen!
Happy scribing!
