It sounds like you are doing MP soap right now. There are different opinions about applying oil to the inside of your molds before pouring in your soap base as some believe it makes it easier to unmold your soaps. I've read about this in at least 2 MP books I have when I first started. I feel that oiling the mold first makes my soap sticky after and didn't make a difference making my soap easier to unmold. It actually depends on the type of mold you use and the temp you pour your soap, although sticking your soap in the freezer for a few minutes after actually helps in unmolding especially with high detailed molds. The typical molds that you can buy in most craft stores have a tendency to melt, crack or break after a while and be difficult to unmold. Also some people feel that the base that you can buy in most craft stores while cheap is also very drying to the skin.
The use of FOs or EOs is mostly personal preference, depends on whether you're trying to stick to all natural (EOs) or not (FOs or a combination of FOs and/or EOs). Make sure that the EO you use is body safe and only to the amounts recommended or less to decrease possible adverse effects.
Just something to consider, but whether you are giving your soaps as gifts or selling them, you are liable for any adverse effects that someone may have using them. Not to scare you, but FYI.
There are tons of resources online for soaping supplies, molds, and tutorials eventhough there a few sites that everyone here prefers. Hope this helps!
