Fingerprint Moulds - best products

Hi I'm new to the silver clay fingerprint making and have seen posts about using siligum to take the initial fingerprint but I would like to know what people feel is the best product to use to take the counter mould to then press into the clay please? Many thanks. x

I don't do them, but for a start put Fingerprint into our search box to see some of the many past threads on this subject. Dennis

Victoria did you find the best product for this?
