I have not, up until this point, used a base of any kind. Nothing against those who do, I just like doing it all myself, thats part of the fun for me. I do however, accept my limitations. I need to start carrying bath/shower gel. I would say 1/2 of my cutomers would prefer it to bar soap. My question about bases is, are they "tinkerable"? Does anyone add anything besides fragrance to their bases? If no, what bases have you found to be the best quality...there are soooo many out there.
