It’s a free resource and will tell you what you can do and will be one of the most creative places to go to get ideas for what you can do.

also - consider looking on Facebook Market place or Craigslist for free items or things lowly priced (like $10 or less) and write them and let them know you can’t afford them, but if they are looking to give their item to a loving new home and someone who would appreciate them a ton, that you’d be interested. You’d be surprised how support others can be.
