Maybe you have seen my first instructable http://www.instructables.com/id/Fishermans-boots-homemade-high-wellingtonswelli/. I think it's good, but not long lasting. That's why I came with this idea.
Again, it is very cheap ... less then 1GBP :)
Step 1: What do you need :
1. foil (for green houses)
3. cardboard and normal paper
As in the first instructable about waders ... you will need some "Crocs"v as well - to put on this boots.
