Linen Canvas

Taken all the way down to base materials, one Linen Canvas is 2 crafting steps deep and needs 3 intermediates — Linen Yarn ×2, Beeswax ×1 and Cotton Yarn ×1 — which resolve to 3 distinct raw materials totalling 7 units, plus 8 crystals.

That bill outweighs 4,963 of the 13,602 recipes tracked here and 557 of the 1,968 Weaver ones, and 4,464 recipes nest deeper.

Only 4 of those crystals go into the final step; the other 4 are burned by the intermediates, so the real crystal cost is 7 Lightning Shard and 1 Water Shard.

The chain crosses two disciplines — Weaver to Lv 36 and Alchemist to Lv 10 — so no single class can finish it unaided.

All 3 raw materials are gathered, and not one of their spots is timed, so nothing in the tree waits on the Eorzean clock.

Linen Canvas is itself consumed by 12 further recipes, spanning three of the eight crafting classes.
