Post-Script: One effect of typing on the roll of teletype paper is getting long-winded, like I'm apt to do, and not having room on my flatbed scanner to get the title and signature in one scan.
I like this blue ribbon, it's darker than I thought it would be at the time of order. As I indicated in the piece, the slightly yellowish tint of the teletype paper works well with blue, since they're complimentary colors, if I recall.
I'm not yet sold on the idea of liquid correction fluid, even if it is dispensed in this neat applicator pen. It's certainly slower to use, and requires care to avoid a mess. Yet this teletype paper does not work at all well with any of the brands of correction tape I've tried. So perhaps for this specific paper I'll continue using it for a while.
It's been fun working with these varieties of correction methods, something essential if we are to continue typing via cloth ribbons to paper; or, become entirely faultless in our typing technique (that ain't happening!). I am looking forward to using the correction tabs.
