Ideal Make-Up Collection Size

I'm on a mission to decrease the size of my collection and get rid of products I'm not thrilled with (and trying to be a tad more minimalist). In my last post, "What's In My Stash? Part 1: Make-Up Collection", I counted every product I currently have in my make-up collection. Needless to say, I won't be running out of anything soon. As you can see from the data below, there are some areas that I'm fairly happy with, and others that need a lot of work. 

What's your ideal make-up collection size?

If I Finish This, I Will Purchase That...

In conjunction with my Project 10 Pan, I have decided to do a "If I finish this, I will purchase that".

I really want to start minimizing my collection and only have items in it that I actually enjoy using. I have too many products right now that I'm just "meh" about. On top of that, there are a few (non-makeup) items that I WANT but really don't NEED. I'm hoping this will help my budgeting and keep me on-track with my spending.

My next goal is going to be to actually count how many items I have in my collection and compare it to how many I'd like to have ideally.

To Finish:	Reward:
1 Eye Primer 1 Face Primer	Hair Towel
2 Concealers	Shower Robe
5 Foundations	Curling Iron
2 Powders	Label Maker
1 Bronzer 1 Blush	Plastic Container
3 Eyeliners	Plastic Container
2 Perfumes	Plastic Container
2 Face Serums	Plastic Container
3 Shampoos	$25 Clothing
2 Body Washes	$25 Clothing
1 Lip Balm 1 Lip Gloss	$25 Clothing

Here is my rationale for the rewards: 

- I currently have a hair towel but the button broke off. It's still usable but I'd like a new one.

- I have an ancient shower robe that is shorter than I'd like. Ideally I'd like a long terry cloth robe. 

- Since moving out of my parents place, I no longer have access to a my sister's curling iron that I would use occasionally. 

- I will be moving in my new house in May of next year and would like to start packing away some seasonable items. That is what the label maker and plastic containers are for.

- I need to put a cap on my spending and have been finding some really cute, inexpensive pieces from Dynamite Clothing lately.

Are there any categories in your collection that you want to minimize?
