Yep, hemp french terry is great stuff. Most of the diapers I make are made with hemp fleece (Hemp fleece is the same fabric except the loops are cut so it's soft and fuzzy). I use 2 full body layers w/external soakers (it takes a long time to dry w/sewn soakers). When ds was small (and peed tiny amounts all day long) I could get away with using the 2 layer diaper w/out a soaker during the day. It's that absorbant! (But now he pees super soaker amounts less frequently, so I need a soaker)
That looks like a decent price. Check shipping though, because it's heavy. Hemp fleece weighs almost a lb per yard w/packaging.
And make sure you get enough. It shrinks ALOT. You'll love it for night dipes and doublers so get at least 2-3 yards.

AND PREWASH TWICE!
I love hemp...
