Help needed - what material to pack out a case?

[shoulderpet]

Hoping someone can help, what can I use to pad this case out so my Mustang fits it snuggly (and if you can advise where I can purchase from that would really be appreciated), I appreciate any help with this, thank you

I have a EBMM USA sterling which I transport in a SKB iSeries case when I fly.

The case is designed for a larger body than my Sterling.

I pack it out with pipe insulation foam. (amazon or screwfix)

One piece around the body of the bass.

It works a treat.

Mac&cheese will fill that right up

I used some rolled up tea towels to pad out cases when needed. Just bought a pack or two from a supermarket, and any that weren't used in the case went into the tea towel drawer.
