Built into the game all the skills have a secondary skill that feeds them, except for tailoring and enchanting. Tailoring is simple because you get mats from very regular drops. Enchanting you can only DE greens or better.
Well, the answer really is Tailoring is the "secondary" skill that feeds enchanting. You can very easily make green items to DE using your spare linen, wool, silk, etc. I wanted to even point out one particularly good one
Black mageweave headband
3 bolts of mageweave 1.5g
2 heavy silken thread 40s
so this costs 1.9g to make and DE's into 2.19g of mats according to the median prices and % DE chances on allakhazam.
Try it out yourself. :)
