many many years ago I found what they called a 'silicon baking' mat. its been so good, its about half the size of Dave's.
the raised lip is a must, its saved my needle chuck from ending up on the black hole of the floor more times than I can remember.
For anyone interested, Amazon/Temu/AliExpress all have the 'silicone pet mats' (just make sure it has the raised lip. )
