.. Getting the canvas out of the vase

You need more reach.

Search through the house. ( Pick up a poker near Lucy's fireplace )

But you need to wrap it to something soft.

Have you investigated the Fig Hall more?

There's that interesting photo of the fireplace on the wall.

But, did you try to pick it up?

Talk to Howard, he will give you a tote bag.

Wrap the poker to the tote bag.

Then use the poker in the bag on the vase.
