Help with Cleckheaton bootie pattern please!

[Pixeygirl]

Hi all,
I'm doing booties from Cleckheaton book no. 423, pattern 2 (sorry, no link it's from a book), and am stuck, please help!
The pattern starts at the ankle, I have done the ankle part and shaped the instep. The instructions are as below:

SHAPE FOR INSTEP:
Work in stocking st. for rem.
Next row: K 20, turn, P8, turn. Cont. on centre 8 sts (leaving 12 sts on needle at each end) and work 14 rows stocking st. Break off yarn.

SHAPE SIDES:
with right side facing, rejoin yarn to end of 12 sts at right edge, knit up 10 sts evenly along the first side of instep, knit across 8 sts from end of instep, knit up 10 sts evenly along 2nd side of instep, then knit across rem 12 sts... 52 sts. Work 7 rows stocking st., beg with a P row.

I have done all the instep, the part I'm stuck on is where to start when I'm shaping the sides - if I have the right side facing me, I have 12 sts on the left needle followed by the centre 8, then 12 sts on the right needle. So... where do I start, and what on earth is 'knitting up' when both needles are full?
Apologies if this is a duh! question, I'm a beginner.

Thanks!

Knitting up is another term for picking up stitches. So take another end of yarn and pick up sts along the side of the instep, then knit across your 8 sts, pick up more and knit across the last 12. It wants you to start on the other edge of where you are, so you'll have to put some sts on a holder.

Awesome, will give that a go. Thanks Sue!

Ooh, one more question - sorry Im sure this is glaringly obvious but I can't seem to figure it out - do I start on the left side or right side of the instep? It's on the left needle when right side is facing.

I dunno, I've never knit these so don't know where you're at. Whichever edge will make the sts work out right.

k, thanks Sue will have to experiment
