Yes, I mean the heads weren’t visible, and the string arranged them that way after Rosa died, the chairs were turned and in a different position before.
The rose could’ve been taken from the garden by Rosa, thoughtful about her romantic status.
There are two possible ways where Rosa ended up in that position.
1.She put herself in that position because she wanted to sleep or stay on the table for I don’t know.
2.She wanted to see the blades better.
But both are simply absurd.
The setting of this crime is really strange, that’s why complex mechanism were the first thing I thought of. There aren’t many other possibilities left, anyway.
EDIT: noticed this is the 100th post, yay.
