For the new soapmakers amongst you, my advice would be to make your first batch a totally plain, all purpose soap. I have a soft spot for all olive Castile, but thats just me, .
well, i've not made soap before but i too have a soft spot for olive soap... in my opinion it's an amazing soap for wool and other fabrics. we used olive soap as a wool soap on our daughters wool wraps that we used with her cloth nappies. it took out even old stains without too much work.
we started using it on jumpers and our wool coats as well, excellent stuff!
