Pre-chewed gum and a scrap of paper torn off your kneepad might also
work nicely. I've been thinking of tossing a pad of small Post-It
(tm) notes into my bag. Even in VFR, I would like to be able to cover
the ASI

Correct, I neglected to have mine handy ... a preflight error.
When operating single pilot IMC in light chop (daytime thermals),
with my instrument covers behind me in my flight bag on the seat behind me,
I am _not_ about to stop flying
work with what I have left.

Before non-pilots get confused, there are many different scan patterns
and rules to define when you switch between them to maintain

There are many different failure modes, that is one of them.
That's what happened when I had a bearing failure (VMC).

I have never dealt with a vacuum failure, so I don't know how
realistic that behaviour is, but I have
