I'm a left-handed beader but I've never seen the article - I'd be interested to know what the tip was!
I have real trouble following patterns left to right, as I tend to work from right to left (I think this accounts for why I do such a lot of freeform; I can make it up as I go along). I have even more trouble when it comes to writing down my projects so that they will make sense to right-handed beaders! Sometimes I have to hold a mirror to the work, or scan the diagram or pattern onto my computer and flip it over so that I can follow it from right to left instead.
