Actually performing the skill is the best way to learn, but skill books can work fairly well. Make sure your Sim has nothing to distract him/her (leave the knitting basket out of the inventory!) and it can help if you can get the Sim Focused before they start reading. The Peace and Quiet lot trait can also help with reading; haven't tested to see if Study Spot (from DU) has a factor as well.
