Pattern Help Please :)

I am a newbie to knitting and I am just attempting my first real size cardigan,
This is the link to the one Im doing

I am a bit confused on the sleeve part of it, this is what the pattern says
SLEEVES
With WS facing, working across first Sleeve sts only, join yarn and work in St st (k on RS, p on WS), decrease 1 st each edge every 4th (4th, 6th, 6th, 6th) row 4 (4, 4, 5, 6) times – 26 (29, 32, 33, 34) sts.
[COLOR=“Red”][B][I]Work even until Sleeve measures 4 1/4 (5, 6, 8, 9) in. (11 (12.5, 15, 20.5, 23) cm[/I][/B])[/COLOR] from dividing row, end with a WS row. Work 4 rows in Seed st. Bind off.

Where it tells me to work the sleeve till it measures 41/4 inches, im a tad confused as to where to measure it from, can someone point me in the right direction please

Measure from the point where you put the fronts, back and second sleeve on holders. It’s the same row where you joined a strand of yarn and started purling across the first sleeve on the WS. Measure down along the center of the sleeve, not along the sloped edge.
Very cute sweater!

Oh great stuff thanks ever so much, I really appreciate it, I can carry on now lol :slight_smile: xx
