Storage issues

[Leman]

I use the bases Simon Miller supplies, drilled for rare earth magnets for my TtS 28mm armies. Otherwise  I use the rubber rolls used to prevent carpets from slipping to line my storage boxes.

I have all the drawers in my storage chests lined with Grip Mat, which sounds similar to what you have described.  It can be seen here  https://www.homebase.co.uk/multipurpose-grip-mat-ivory-120-x-45cm_p373922.  It works really well.

Aldi has that at the moment - might have to have a look!

Very similar to the stuff I use, except mine is a charcoal grey colour.
