Reply #25: Get a glass jar and some cardstock paper

[supernova]

Move the Warhol print till you can see the spider. Carefully. You don't want to upset the thing.

Put the jar down over the spider.... You can do this slowly or fast, depending on if the spider is aggitated.

Insert the card under the glass to cover the bottom opening and trap the spider inside.

Take the thing outside and let it loose.
