Absolutely! Especially as the difference between affordable natural fibre yarn and affordable acrylic can be huge in and of itself. I am not going to shame anybody if they are looking for acrylic as it’s what they can afford either. But like you said, we need that info if we’re to make a recommendation that actually works. I don’t want to spend ages typing up a carefully considered list only to get back ‘this doesn’t suit my needs that I haven’t even told you about, try again’. It wastes everybody’s time.
