"Improved" Spider Silk

What's that? You want to sell spider silk in Valencia? I mean, of course you can sell them for a high price at the moment! But, I'm still in the middle of making some improvements... I mean, even before I thought of making these improvements, the cloth weaved from these cobwebs became quite popular, indeed. Hmm... I see I'm not getting through to you. I think you need to learn more about the spiders who spin this spider silk, first. There are plenty of these critters crawling about outside the village. Go out and learn their Knowledge before we continue this conversation.

Ah, you've learned much about the spiders. I think we can finally get to the heart of our conversation. Before I made the improvements to the spider silk, it shared a fundamental weakness to heat, which, regarding Valencia's hot sun, made the cloth it was weaved into worse than the cheapest fabric. However, my new-and-improved spider silk are heat-resistant! They're sure to become the next "hot" item in Valencia!
