Pick up and purl???

[mamaterry]

Hello,
I am knitting a baby bootie pattern in the round on 2 circular needles from the cuff down. http://www.knittingonthenet.com/patt...ootsribbed.htm
So far, so good. Did the cuff and instep. Picked up and knit 11 along left side of instep, knit the next 11 st ,then purled the next 11 st but I don't know how to do or find any info on the next bit, 'pick up and purl' next 11 st (from right side of instep). I know how to pick up and knit but not how to pick up and purl!!!
Any info and help would be greatly appreciated.
Thanks.

P.S.
I am new to this forum so I will introduce myself. I am a happily married baby boomer living in CT (but want to move to NH). I have been crocheting since the early '70s and always wanted to knit but could never master the 'american' method of knitting. I could crochet a mile a minute but was at a snail's pace knitting until I got Maggie Righettiis book 'knitting in plain english' in *2000. The 'continental' method was my cup of tea. Maybe it is more similar to crochet movements of the hand than any other method. Anyway works for me.
Thanks again.
