i have seen that site (knitting fool) before, and i find the directions there hard to read (and i generally don't have trouble reading directions. (i have designed stitch patterns, and written them!)
to understand, i cut and pasted (i used to re-write or re-type!) any pattern i didn't understand--i find that is the best way for me to learn.
(meanwhile you should always, always swatch a pattern before you start..
get some cheap cotton (kitchen cotton) and make yourself washclothes, (dish clothes if needs be) or coasters (you can always use more coasters!) and always swatch a pattern in cheap yarn to learn it..
then you don't have to frog your good yarn!
