The fountain pen is my favorite, it can go from a hairline to a bold just by varying the pressure. It is the closest to a dip pen I've found. I like waterproof ink so I can do add watercolour wash over it and currently I'm using Platinum ink. I flush the pen out every few weeks since I paid way too much money for it and want to keep it working nicely. There is a whole world of fountain pen collectors, many of whom are snobby and tedious.
The uni-ball eye pens are nice. I think they are called "vision" ouside of Asia. I tried them out because Tommy Kane likes them and they are really nice to draw with. I've got them in black in fine, micro fine and ultra micro. They are waterproof and come in a bunch of colours.
The muji mechanical pencil is a copy of a pentel 500 pencil but without any logos on it. I like a 0.3mm led for sketching in an A6 size sketchbook.
The Koh-i-noor clutch pencils is ridiculously chunky and came with graphite, charcoal, sanguine and chalk refils which is great. I use it mostly for life drawing classes. I'm thinking of getting another holder since I'm always swapping between the sanguine and charcoal.
Fabric dyes hey? I've seen those in the art store and never thought of using them. Might give it a try with a dip pen.
Here are the three pens which I use the most:
* Stabilo Point 88 fine 0,4
* Staedtler Triplus Fineliner
* PaperMate Flair
My favorite will always be the PaperMate Flair, especially for their black pens. All three brands come in a wide variety of colors. I hope you are still here on IUOMA, and that I have answered your question.
All the best...David
David, many thanks -- I've used one of the pens you mentioned, two not, and will give those a try. I'm here on IUOMA only occasionally now, though I miss it. Very good to have your input, thank you again.
