i've only recently started levelling my enchanting (after hitting VR2) -i'd managed to level it to 10 or so just from reading bookshelves whilst i levelled.

but now, at veteran levels, there are only high level runes to be found, i can't craft any without sinking large amounts of skillpoints into the tree, which i can't do until i level it...

but i have found the quickest way of levelling it, is to deconstruct enchants from mobs. i found the delves in cyrodiil to have great droprates on enchants and they are easy to farm, as the mobs are level 50 and not veteran rank.

otherwise it's a case of going right back to the very first zone (the starter island essentially) and running around for hours on end to try and fine the runestone spawns - which is just tedious busywork and not exactly how i like to spend my gametime...

at least with the mob farm for enchants to deconstruct you get money, armor and weapon drops - which are all useful in their own ways

edit: at one point i also reseorted to buying low level enchants from a vendor to deconstruct into runes, which i then constructed enchants from to send to my g/f to deconstruct. i didn't get much xp this way, but she did.
