I would also get new main-hand and off-hand tools. You basically need any stats it may add to HQ stuffs at your level. What I find helps though is to level Botanist to 32-ish to gather flax yourself and mix and match the HQ flax with the NQ flax in order to HQ the linen yarn and undyed linen needed to make the final item. I don't think I had any problems leveling weaver as my first 50 crafting this way but I had all other crafts at 15 too. Also, always make the best gears you can wear HQ first before attempting anything else. This helps in the long run as you can spiritbond it faster as well as having higher stats when you work on items for leves or quests.
