Shading the garden

"Stupid system! Doesn't even tell me what to do!" She cursed as she slung the rope around the hollow tree's branch. 

She pulled the rope's end and tugged towards the side, making sure that the knot had fallen into place. The wind had picked up as soon as the sun had set. Despite the cold, she was out in the garden, trying to save her plants before the rain descended. 

It didn't take her much time to figure out how to knot the cloth and the rope together on all four sides. She had watched the servants build a shelter of a similar kind behind the kitchen to expand their working space. But figuring out where to tie it to was a problem. But soon, she had come up with a solution for that as well. 

The metal pillars that the lanterns hung on were quite sturdy and made a suitable pole for her to tie her ends. Seeing how the tree was right in the middle of the ground, she had to somehow pull the cloth over it, making it, in turn, a sturdy support from between.
