Having used just about every throw away drawing pen and thrown away lots of expensive technical pens, and cursed them many times for not writing or for leaking, I decided to splurge and buy a good fountain pen. I got a Sailor 1911 while in California and love it. I've been doing a good bit of sketching with it, but I only have non waterproof ink and haven't been painting what I've drawn until yesterday.... just so I'd have something to put here.
Here it is.... another view from my window. I first drew the scene and then just used water to bleed the ink and put some more lines in after it dried.
I've been looking at Noodler Ink to order, which from what I've read is waterproof when it reacts with the cellulose in paper and will not harm the pen.
I finally finished a commissioned painting that I've been working on (mostly avoiding) for months. You can see it by clicking HERE
