Hmm. I used to use a fountain pen sometimes. I haven’t in years. I should try again and see what i did. (Yes, I’m left-handed.) I think i tried to use absorbent password, though.
Your password is too weak. Please choose one that is less absorbent.
Mountain of Ink has a collection of fast drying inks. That isn’t perfect however faster drying ink will limit the chance of smearing.
Paper. 
As long as your absorbent paper password isn’t a blotter; those get everything backwards. Which will never work to let you in.
Can you hold the pen so the contact point of your hand with the paper is positioned under the line, if you follow me? I assume you have tried this and it is not comfortable? The pen itself does not have any chirality or handedness.
They would if their palms were resting on the same line they were writing. Cf. tutorials in Arabic calligraphy: the first lesson is on how to hold the pen and write the basic strikes.
You can use quick-drying ink, of course.
Either way, it is not necessary to jam the nib into the paper; no pressure should be required. (Perhaps it is more a matter of upstrokes vs. downstrokes as RTL versus LTR?)
Aw, you’re kind! Yep, I’m a lefty, and also a dork.
Sadly, I don’t have much help here. My handwriting was so bad as a kid that a specialist came in to help me. Unfortunately, my stubbornness was so intense that it didn’t help much. The only thing that really helped was learning to touch-type. To this day, my hand cramps up something fierce when I try to write without smearing any sort of ink-pen.
As for teaching handwriting to kids–this has never been my forte. I can teach ‘em to memorize poetry, to use spreadsheets, to devise plausible ecosystems, to discuss literary tropes–but handwriting? Oh boy, I hope they have another teacher who can do a better job with this.
This is true. When i played with a lot of pens, i used a very light hand, and the fountain pen nib doesn’t get pulled or pushed, it glides gently over the paper. That’s one thing i liked about using fountain pens.
Thsnks. The ink is wet for several lines, even if I slow down. Thinking a finer nib might help, and I’ve located one, but I’ll try other strategies before buying.
I’m trying to change my hand posture, but it’s painful.
I must be the world’s weirdest left-hander, because I’ve never had any trouble writing with any sort of pen, or smearing the ink.
The way I’ve always done it is to hold the pen so the rest of my hand is below the line I’m writing, with the side of the hand resting on the surface. That keeps the pen nib and the writing completely free of my hand, so there’s no chance of any contact or smearing. It just seemed so logical to me, I could never figure out why my other lefty friends would have such trouble, and especially why they would contort their hands into that uncomfortable-looking hook position.
I seriously wonder if I’m missing something, but given that I’ve been doing it this way for decades, I’m not likely to change now.
I do push the pen, though, rather than pulling it, and I have had trouble with fountain pens catching on the paper. That’s not an inconvenience for me because I long ago gave up using them–not because they aren’t comfortable or I don’t like them (I adore beautiful fountain pens) but because I don’t write by hand often enough to keep the ink from drying up.
That is what I meant
With certain ink/nib combinations I have run into the problem where several lines on the page remain wet for a while, which is a problem if I am writing in a notebook and want to turn the page and keep writing!
