No, there is a lot more work for Silver Brocades.

Tomato relish require 1 HQ (can be done without HQ, but more reliable) tomato and ~1 Noble Grapes to be farmed. The rest of the materials (except shards) is vendor. Quicksynth the Dark Vinegar and you are ready to go.

Silver Brocade require 4 Crawler cocoons, 3 Silver ore and 2 Effervescent water. None can be bought by vendor. You will need to craft both the Twinthread (x2) and quicksynth the Silver Ingot. You can macro craft HQ Twins without food, but it will require a lot of time crafting them and they require crystals.

And in comparison:

Spruce Plywood require 3 Spruce Log to be farmed. 4 Aldgoat Horn can be bought by vendor. Macro the Lumber (x1) and quicksynth the Glue (x2). Require half the amount of Crystals and less shards as well.
