Thank you was not sure what to call it so I went with something close.
As for my first way I used model Magic around the pool to connect with the carbord then some around the edges but it fell of. Maybe becuse it was not dry. It was a bit top heavy.
The second was the same with a bit more model magic along with some sapports but it completelt fell off and was supper heavy proble used almost three pounds on it.
Hi hope you all the best in your day and night
