Subjunctive KoL   Subjunctive KoL: FrondItems

To get palm frond items, adventure in the Oasis to get Hugo's Weaving Manual. Read it, then continue adventuring in the Oasis to get some palm fronds. Once you've gotten a bunch of them, you can weave them together (either by using the Manual or by using "use multiple" on the fronds) to obtain various items.

There do not appear to be any items makeable with 8 or more fronds.
