Honestly, this experiment ended up being a little expensive, since I didn't have any of the materials beforehand and also had a failed attempt. If you're on a budget, I would definitely practice tie-dying on some rags or old clothes first, just to make sure you like the pattern and color combinations. If I had only bought the sweatshirt, shorts, and pink dye, my total would've been about $20 – so this project definitely can be cheap if you're careful.
Overall, I definitely think it was worth it! I had fun and now I have a cute new loungewear set. I'm definitely going to tie-dye some other items since I have so much leftover dye! I also think this is a great activity to do with your family or roommates.
