With Guild Support from Clothcrafting and the Glasses, these seem to be tier 1 HQ with 100+3 Leathercraft. Clothcraft level required doesn't appear to be higher than 53.
This is the HQ synthesis of the Austere Hat, the JSE headgear for Summoners. The recipe is:
Earth Crystal
Velvet Hat Yowie Skin Ram Leather Sheep Leather Rainbow Thread
Level 90 Leathercrafting at an absolute minimum. Some clothcrafting is assumed. The presence of Rainbow Thread suggests a very high level (60) of Clothcrafting is useful in sucessfully making this or the Austere hat.
