A "jumper" translates to "sweater" in the U.S. right?
Just making sure. You mean a pullover sweater/jumper, rather than one with buttons down the front.
OK......since you're new at knitting, and BTW, KUDOS
to you for jumping right in....no pun intended
So.....do you mind, or prefer seaming the pieces or would like to do it in 1 piece? Top down or bottom up? Bottom up and seamed is usually done for a first jumper simply because it's knit flat rather than in the round.
Don't let these questions bog you down, I'm just thinking out loud.
Are you on Ravelry yet, that's a perfect way to search for patterns. The pattern will say something like:
XS [S, M, L, XL]
Bust measurement: 30 [32, 34, 38, 40]
So you will know which one to make for yourself based on your bustsize. If you're a size 2, then probably the XS (in my example above).
I searched Ravelry for the highest rated, knitted flat sweaters, rated "easy" for beginners, go here to see the result
