How to get the three sticks of dynamite in West of Loathing?

I've gotten the first stick by learning Dickerin' through the book mom gives, then the second through trading a needle. How the heck do I get a third?

Solution 1:

This means that you must grab the needle from the haystack at your house in order to get the reward, as you'll trade one needle for a stick of dynamite, use one needle to get the crowbar from the toolbox, and then this final needle on the reward.
