Ginny's King's Cross Station Sweater, Sorcerer's Stone

While we only see Ginny in these moments at King's Cross in The Sorcerer's Stone, Ginny is wearing a Molly-made sweater just like most of her brothers. Ginny's cardigan appears to be made in a few asymmetrical color blocked pieces that are sewn together, giving the true feel of a "Molly Sweater".

I couldn't find a pattern for this sweater, but the pieced look wouldn't be hard to replicate on any cardigan pattern.

Molly Weasley's King's Cross Sweater, Sorcerer's Stone

The first time Harry meets Molly Weasley, she is wearing this amazing fair isle cardigan. From these first scenes, Molly's knit wear speaks to her desire to use every scrap, her love of color, and especially her fondness for the handmade.

A Ravelry search left me with no links to a pattern for this exact sweater,but the construction appears to be a basic seamed cardigan with an afterthought button band.
