Those are great materials! Some others that like to use are cupcake liners, natural raffia, paper straws, shower rings, rope dog toys, baby toys, wooden rodent chew sticks, brown paper lunch bags, and even that brown packaging paper that you can sometimes find in your packages. Here are some examples of toys that I made:
Used: paper straws, plastic beads, thin rope. All materials are from the dollar store.
Used: originally, just shower rings. The foot toy and clips somehow came later...
The shower rings were found at the dollar store.
I really like how these turned out; credit actually goes to Feather Beautiful on Youtube.
Here is her video. Instead of a wire, though, I used zip ties.
Used: Cupcake liners, baby bath toys, plastic beads, zip ties. Cupcake liners are from Walmart, everything else was from the dollar store.
Here is a dog toy that I hung up on my stand. I also have one in my budgies' cage. I got them at, you guessed it, the dollar store!
Here are some plastic baby links and a cute froggy put together to make a climbing toy. I got the frog and 24 colorful links from the thrift store. Once I came home, I washed everything really well with warm water and dish soap.
Used: old round swing, that brown packaging paper, a random twine-like ribbon, regular twine, and raffia. Tbh, it kind of looks like a wreath. I only remember that the raffia and twine was from the dollar store.
Finally, we got the play corner of my budgies cage. The homemade toys are the paper towel/toilet roll "garland," the ladder, and the brown paper toys on either sides of the ladder.
For the toilet paper tube garland, I simply used toilet paper tubes and twine. The twine was from the dollar store.
For the brown paper toy, I used zip ties, plastic beads, colorful rodent chew sticks with holes already drilled in the middle, and either paper lunch bag pieces or that brown packaging paper. The colorful chew sticks were from Petsmart (in the rodent section!), the paper lunch bags were from Walmart. Everything else: dollar store
For the ladder, I used short pieces of natural wood branches that I collected and a fabric belt that we somehow had without the dress... I tied the branches together
using this method.
