Welcome Deeluxkilts,

I just flat gotta strongly disagree with your statement about polyviscose. Not wool for sure (I have 11 hand sewn wool kilts) but its the best there is for a non-wool fabric to use for kilts. Have owned 22 Polyviscose kilts and can speak from experience.

Assuming you're not mixing up acrylic with polyviscose. If you meant acrylic then I'd agree with you.
