Once we had washed and taken the labels off the bottles, it was time to cut the bottoms off and start to stack them onto canes. We stacked the bottles one inside another with a garden cane supporting them through the middle. The last bottle had to be reversed so it faced the opposite way to the others enabling it to fit with the cane sticking out of the tops of the bottles.
Our next job is to attach the canes and bottles to the frame of the greenhouse.
