Rejoining and picking up stitches help please?

[Kell]

Hi all

I'm knitting a pair of boottees for the first time! Very new knitter I've done a whole heap of rows and then had to divide to knit an instep but now have to rejoin all the divided bits so its like i've got 3 lots of knitting going if you can understand what I mean - 11 stitches then 7 then another 11. The 7 are longer as this was the area worked on now I am meant to pick up 6 stitches along first side edge of instep, pattern across and then knit up 6 evenly along second side of instep and pattern across - eventually have 41 stitches. So after all that my question is how do I knit up the sides as in pick up the instep?

I hope I'm not too confusing and someone can help me fast! As I really need to finish them!

Thanks, Kell
