I think you can "recommend" certain needles, thread etc. but it will eventually be a personal choice based on many criteria.
I'd love to know about 1/4 foots on machines--used to draw the line in pencil. Grain of fabric--HUGE to know about, especially when it stretches.
I would have also liked to have had a bit of a discussion about lights, darks, and medium color fabrics. I'm a fan of darks and to actually buy light and medium colors KILLS me, but sometimes in order to get the look you need to understand color value. I still stuggle with this.
HTH,
