While I'm still having a lot of used stuffs as storage (old jars/boxes), I eventually bought some ready made storage organizers.
One of my favorite is drawers with wheel. Perfect size to place inside my closet. I bought 2 of this kind of drawer from craft store nearby when they have it on big sale.
Easy to install, light weight, and portable. I do like light weight stuffs in my studio. I often rearrange my studio for many reasons. Sometimes because I just got more stuffs, sometimes just because I feel bored with the current arrangement :-)
I labeled the drawer to make easier to search for certain thing.
