Sustainable Party Supply & Decor Recs?

Not exactly a fashion topic… but it’s design-related, so I’m hoping this lovely group can help me out. I’m planning a kid’s birthday party this summer and I’m struggling to find cute party supplies (plates, cups, etc.) and decor. I know there is the typical beige-colored compostable tableware and I am fine using that if need be, but wanted to see if any sustainable and cute party supply / decor brands exist out there. Thanks!
