Go talk to Armorers and Blacksmiths and see if you have any diagrams they can make you weapons/armor off of. There's diagrams all over the map.
Also keep in mind any ingredients you don't have you might be able to have the NPC dismantle other stuff into it....like a cup into a hunk of silver, 4-5 silver = a silver bar, 4-5 bars = a silver ingot, etc.
That's not an actual recipe just giving you an example.
Also there's quests for Witcher gear. I think the first one is at level 6. Seek those out ASAP, it's the best gear for 3-4 levels. I got all Witcher armor and a Witcher sword diagram from a quest, I think it was callled "Griffin School".
