My children's school wanted outdoor stools and asked me if I could make them some. They wanted something like my ottomans but smaller.
Enter Trishaw tires! In Asian countries Trishaw or Three Wheelers are commonly used for transport. We have loads of Trishaws and hence loads of waste tires! Luckily for me there was a tire shop near my mom's and they happily gave me 24 tires FREE!
Now I had to make 6 stools for school and I wanted to make another 2 for me. I seriously couldn't see myself drilling and joining all these tires! My arms would kill me!! So I looked for other options and came across 2 part epoxy glue which also glues rubber. Yipppeee! saved :-D
3 tires per stool
2 part epoxy - I used EPI FIX. I'm sure you could find other options for this in your country.
2" sponge foam
9mm plywood for lid - You could also use the lid of 5L paint buckets. ( I couldn't find any at hand else I would have used it
Leather/ synthetic leather
Heavy duty Stapler Gun
