Tailoring

[Xenocida]

Hi, new player here with a question.

I've just started leveling my Iskar Necro and based on some advice I got I've been leveling off spiderlings/spiders and saving the silk to sale when I eventually make it down to EC.

My question is, I understand the value of this silk is it's used for tailoring, but I'm just wondering, would it be beneficial for me to use it to skill up tailoring for myself instead of selling? What are the long term benefits of it and would I eventually see a return on my investment?
