Here in Italy embroidering is still fashionable, LOL. At least, cross stitch is. I can't even mend a stocking, but i can cross stitch quite well.
But, with a quick look i'd say Af used other techniques, maybe tent-stitch (also called in a french way, petit point). It's not so different from cross stitching (but i can't do that) but it allows more complicated drawings. But i'm not skilled enough in embroidering to say more, and i'm not even sure she used tent-stitch.
As long as crocheting is concerned, i can tell you more. Here it's pretty still used, you know. I can't crocheting, i admit (on the other hand, i can knit, lol) but my mother can, and very well, too. I've so many small sweater made by her, and tablecloths, and even pillows! So, i can ask her to know more. She says crocheting is very easy, and you can do wonderful things with such an easy handwork, that's why she loves it so much. Maybe it's also why AF loved it.
Gosh - thinking of AF crocheting in my mind means seeing my mother with AF's clothes on (my mother is fair with grey eyes just like AF, you know, lol)! Terrifing image!!!
