Woodburning Supplies

I have done a little woodburning. My son is interested in it too. He's 12. He has bad heart valves. He cant do much physical activities like his peers. He gets very upset when he sees his siblings doing stuff he cant. I have been trying to find something for him to do to help with his spirit. I am trying to find some supplies for him to use for woodburning. I cant afford to spend alot with our limited financial situations. Do you know what would be good to start with? Do you know anyone who might have some supplies they cant use? Please email me at [email protected] if you have any ideas. Thank you Tammy
