Mother always, and still does, write notes in shorthand. Gregg Shorthand.
Sure you could do Fraktur. Most of it is the equipment. Get an ink pen and a flat nib. Hold the nib at an angle usually about 45 degrees. Dip the pen lightly into the ink and practice making a few strokes without making blots. To start the letters, make a small horizontal 'Z' shape for the tops of letters that have a vertical stroke. Then make the vertical stroke down. (or make the vertical stroke and then put the 'Z' on top, which ever way you find more comfortable) Make a small 'V' shape at the bottom of the verticals. Keep the nib at the same angle for the whole thing. Easy peasy! Kinda like cables in knitting, it's astonishingly easy and folks are more impressed than the amount of work it took to make it.
