Ivra, may I suggest separating the Arrow and the Arrowhead recipes in the .pdf? It's very messy right now and honestly virtually all Arrow recipes are just Arrowhead + Shaft, anyway.
What's important is to list how to make the arrowheads, so while I think you should definitely keep the Arrow recipes for completionism's sake, they should be separated. They can still be in the same section, just Arrowheads first and Arrows second.
Also, the .pdf should include the legend (explaining "HL" and so on).
