Where to find small pieces of foam

[RobertInOntario]

Do you mean the pink or blue foam that is sold in sheets or softer " cushion foam " such as you might have in your couch . For the latter , I get mine free ( scrap bin ) at an upholstery shop .....for the sheet stuff , I got some broken bits free at Home Depot .

Yes, I'm referring to the pink or blue pieces of foam, so expand my layout board. But, since I'm just thinking of slightly enlarging it that I could use bits of the white foam.

When it's done, I plan to place it on a more solid plywood baseboard -- right now, I'm only using the piece of foam!

Thanks, Rob
