Yes, yes! Hemp fleece is much more absorbant than jersey. Of course it's thicker, but I figure in the end it all works out. If you're really trying to get exact areas of extra absorbancy, then hemp jersey is easier to fold and such, but if you're just tri-folding, hemp fleece is super! I got some of it myself and have been making my own doublers/inserts! MUCH, MUCH cheaper! Heck, you can get a yard of hemp fleece for just a bit more (maybe $2 more) than you'd pay for a new JB insert!!! And with a yard, you'll get quite a few inserts!
