Which budget-friendly materials can I pick for my dad's cremains?

My father-in-law has departed, and we were making arrangements to lay him to rest. My mother asked my brothers and me to arrange everything. I enjoyed hunting and woodworking, and I was thinking of getting him an urn to memorialize his love for these things. The problem is that there are so many options, and all I want is an urn that fits within our funeral budget.
