I Made my first wool caps today, and when I went to improve them after the first improve action with yarn I could not improve them further. The inventory screen does not list any tools or materials to use. and this is the event messages I got after improving them After you finish improving the item you get a blank return in events where you normally receive a message telling you what you need to improve it next. Examine does not show any items you can use to improve the Item with either.
