Before I dip a toe into the colourful world of mica - I’ve been watching the soap queen and I feel patterns are in my future- I would like advice on how much mica in approx 1kg soap -2lb ish- and roughly how much I would expect to pay for some decent ones. I am in the UK but just ball park advice really appreciated. I checked Amazon and of course it’s flooded with suggestions and I don’t know where to start.
