Hi guys this is very a very simple project, i have lots of off cuts from my bottle green house, so all i do i find a bottom and a top that fit snug in each other and silicone them then i cut a hole in the front to allow small birds to enter, then i mix some PVA glue and coat the bird house, then i sprinkle a thin coat of beach sand all around the glue shaking off the excess,this is done three times. then a hole is drilled in the cap, find ya self a nice piece of heavy wood for the base, and an old tree branch drill the holes to hold the bottle, at different lengths to hang the bottles and there ya go, easy eh !
