If you know somebody who is allergic to wool - and they are willing - they could hold it and see if it triggers a reaction. Otherwise, microscope. You can buy pretty good microscopes these days, including some that plug into a computer via USB so you can capture images. Wool is scaly like hair, synthetic fibres are smooth. Rebecca

My uncle sent my 2 month old son a gift of a hand knitted cardigan which he bought from a charity stall. without a label I have no way to know if they have used wool or acrylic yarn. I know I can test using bleach or a burn test but I don't want to damage the garment is there a non destructive test I can do on a finished garment?
