i have a running list of what my mom has on my sidekick's notepad. on my computer i keep a huge excel workbook of my stuff! it has all different pages for different things, ie one page for face, one for eyes, etc. i also have a page for my wishlist too!

on my main page, which is the whole collection, my columns are as follows:

item, formula, name, description, quantity, limited edition, notes, collection, paired with, date purchased

it really helps to keep everything organized, and to let me know when i have enough stuff for b2m!
