Sulli, your functions vases sound like such a wonderful idea, looking forward to seeing them once your work is available! Hope you share pics here or a YouTube video. You've made your garden into a beautiful space, a rose garden will be the perfect addition!
Jasmin, do you agree with your neighbor that a water feature would complement your garden? The sound of water in the garden is so relaxing, even if the source is mostly hidden. If you decide to add one it'll be so fun to see how you integrate it, whether it'll be a prominent feature or in a more supporting role!
