At a loss of ideas to quickly level enchanting from 90 to 100. Any ideas on the best way?

Also, one of my characters as about 50 empty grand soul gems, which beasts have grand souls?

I found at that last leg I had to start using common and greater soul gems cause petty ones just weren't cutting it exp wise, also it helps to do a bit of smithing, even if you don't have the perks, gather some leather, make 40 or 50 or so leather bracers and enchant away!

I have level 100 smithing and an abundance of gems, it just seems to take so long even when using grands and blacks. I read that if you use higher rated items you gain exp faster...

Mammoths have grand souls.

The best way, or the most 'legitimate' way?

Because the best way is to type: ` player.setav smithing 100

Hunt the mammoth.

Best way, i play on the 360

thats a terrible way to level enchanting. that just levels smithing.

A lot of soulgems + whatever unenchanted, unwanted stuff in your inventory. You can buy clothes very cheaply in cities like Solitude(they have a clothingstore).

Lol mybad, must have misread the title.
