how can i strain micronized kava?

the only affordable store in my area only sells micronized (the traditionals are weak and shitty) but unfortunately it’s giving me the buzz. i can’t always order from european vendors, because i’m quite broke, and i consume kava on a daily basis. so if i would decide to buy micronized is there a way to strain it properly to avoid stomach issues? i don’t have a strainer bag yet, i’ve been using the pantyhose method 💀 but it worked out, so all good for now with the traditional. unfortunately small particles could get through the pantyhose if i put instant in it, as the holes are bigger. should i try straining with an old t shirt? or what’s a good alternative? (if it’s even possible to strain micro)
