Introduction and questions

[xsami3000x]

Hello everyone,

I am new to this, as in havent done anything but read yet but I am taking the plunge now. I bought some m&p soap "avocado and cucumber" that also is a suspension base, and a cool little massage bar mold tray. (There are little fingers around all day or I'd jump into cp). Questions:

What is the limit of additives to m&p?

I'd like to add some ground oatmeal and ground almonds and maybe some almond oil. Would this need a scent or would I just compound too many scents? The base itself really has no scent.

Also what amounts of additives would be recommended?

How do figure the amount that I need to make to fill my molds? Will a water measurement be accurate or close enough?

Thanks so much,

Sami
