I use shoe boxes and any other small boxes I can find for organizers in my drawers. Small boxes that used to hold jewelry or other products are great for organizing small things. You likely have everything you need around your house!
Get creative. Use wrapping paper over small boxes etc etc to make it look decorative. Look up DIY on Pinterest. There are many great ideas on how to organize with stuff from the Dollar Tree.
You could use cardboard boxes lots of businesses will give them to you for free, then maybe decorate them if you hate the look. There's also a lot of free stuff on Facebook classifieds. Going through it all and getting rid of what you don't use often will make organizing easier. Good luck! Pinterest has some good ideas too.
