that didn't really work either, I changed the folders to assets > minecraft > mcpatcher> cit.
but the format you provided didn't change the texture, I am sure that the texture is a .png file, and the properties were changed to:
matchItems=262
stackSize=5-32
tile=arrows
I put it in one version of the pack and in a copy, i changed it to:
type=item
matchItems=262
stackSize=5-32
tile=arrows
both didn't work. I'm starting to guess something is wrong with both of the files here..
Is arrows.properties supposed to be arrows.png.properties? or is it something to do with what version of optifine i use?(Optifine 1.8.9 HD U I7)
In any case, I don't know.
