The design resemble Hyo Ahn's QT rose, but with a pentagonal base instead of a square: if I am correct, you should be able to open and separate the inner petals
Getting the bow to tighten is the hardest step. It may be a bit difficult to express in language, but let's give it a try: First, we need to find the two key "wings". One of them is on the left and the other on the right. When the left and right hands are pulled outward at the same time, the bow will become tight. For example, the key "wings" in the video are one in the lower left corner and the other in the upper right corner. Pulling method: Hold the two key "wings" with both hands, and then use your middle finger or thumb to pull the "lower layer" of the "wings" downward and then outward almost at the same time.
