Did you get it right?
The two clothesline panels contain five visible changes.

The Answer
The correct answer is: five changes involving the quilt square, clothespins, gate latch, clothesline area, and watering can.
Here is why
- In panel B, one upper quilt square changes from a blue star to a plain light square.
- The number and spacing of clothespins along the top edge changes.
- The black latch on the garden gate sits differently.
- The right-side clothesline and towel area shift slightly.
- The watering can detail at the lower right is different.
Why people miss it
The overall scene stays nearly identical, so the changes hide in small utility details instead of big objects.
