Hot air balloon of some sort.
Must be one giant flower...
Color experiment. One shirt was soaked in a mordant and then quince leaves it was yellowish when it went into this pot. The other was brown, probably walnut, not soaked in a mordant. The water is pink from the avocados and there is some silk that was was white as a test strip.
I'll let is soak for a day or so and then let it dry.
