I am currently knitting some booties and am having a problem with understanding what I am to do. The pattern is found here, http://www.shepherdyarns.biz/Media/free_patterns/lace_up_bootees.pdf
The bit I dont understand is ‘SHAPE INSTEP’, where it says to knit up 42 sts. What does this mean, and how do I do it?
Any help would be appreciated
