Envelope. With a bit of masking tape attached. Works better if
you poke the corners inside out first, so as to make it bulge
outwards.



Do you make a hole in the envelope so that the masking tape sticks
itself and the envelope to the wall?

Or should the masking tape be double sided to stick to the wall and
the envemope.

But I'm still not clear quite how you use the arrangement. Could you
or someone else give a bit more detail please.
