We want to make a Cloche with hoops of bent-over plastic water pipe, covered in Plastic sheeting; to end up like a minature Polytunnel for the allotment.
We dont know where to get a large sheet of plastic from here in North West London, so we are going to stick together 'cut-open' clear plastic bags.
What would be the simplest way to stick the bags together, and if glue is the answer; what is the best type of glue to use please? Bearing in mind we would probably have to use lots of it and it would have to be one hundred percent waterproof. Thanks.
