Coco, thanks for more bird toy ideas. My Galah and Grey go through toys on a daily basis. Thankfully we have a table saw and standing drill press so we make almost all their wood and soft-plastic toys except the acrylic foraging ones.
Every single box (crackers, pasta, cookies, butter, cereal, rice, etc) gets repurposed into a parrot toy here. Treats go inside, piece of tape over the lid, and they LOVE it. My Grey meets me at the cage door to snatch it out of my hands. I also put unsalted pretzels inside brightly colored tissue paper and tie the ends with raffia. They look like little presents. I put those in a cheap dollar-store wicker basket and hang off a perch. I put an entire roll of cheap paper towels on the big stainless skewer, too (takes several days to strip that). Construction paper woven through cage bars is also a big hit (also I put straws and construction paper on skewers). There are so many good ideas for homemade toys! I would love to hear even more of what people give their parrots from normal, every-day items.
