Glad to hear that shopping your stash has been going so well for you! In control & in love are great feelings to have about your makeup.. that must be so amazing!
Rotating travel makeup is such a good idea. Kind of forces you to evaluate things because you can't just reach for something else right away. I'm kind of having the opposite experience with shopping my stash. Now that I've gotten rid of some items it's made space to see that some of the others I used to love I'm not crazy about anymore! I've been using things one at a time and comparing them to my favorites and a few things have been purged already. Yay! Purging and shopping my stash have been my main goals right now too. I found a few things from a couple years ago that are so frosty compared to the subtle glow of some of my newer products.. it's just hard to wear them knowing I have more finely milled things. I'm getting rid of a little bit at a time. Also been focusing on using things up! Don't worry too much about the palettes.. you were able to get rid of a couple that weren't working for you so that's great! Holiday sets usually aren't a big problem area for me but with my recent obsession with minis I'm going to have to be more careful this year! That's a good way of thinking about it! I should write that on my MAC bag lol. On my spreadsheet I have them separated by product type in different sheets. Then I have the brand, name, color, manufacture date, approximate purchase date (if I could remember), expiration date. If it's an eyeshadow I have them sorted by crease/transition shades, highlights, and lid colors. The really metallic or foiled shades like the NARS dual intensity shadows or MAC extra dimension or pigments are separate too. I tend to do a really neutral eye or a really bold metallic eye lol. For lips it's nudes, pinks, corals, reds, purples.. etc. That helps me see what I have the most relative to what I actually use. If I always wear nude lips but have more purples than nudes I know I need to cut back.
