I am looking for some soft foam to make padding for my sca helmet, as well as other required bits of padding. Problem is I am having a very hard time locating something I can use for it. Waterslide mats would be perfect but the amusement park I worked at won’t even sell me a damaged one. So I am looking for something like that that is a firm flexible foam for padding or contains such foam that is reasonably priced and might be found at a typical big box retail store. Prefer something from 1/2"-1" thick and has some give like gym tumbling mats but isn’t gonna cost $100 for enough to do my helmet. Prefer not to order online due to time constraints.
Alternatively if there is a type of supplier that deals in such things where I might be able to get a few sq ft without alot of greif. Scraps could probably fill most of my needs.
I seek the combined wisdom of the teeming millions to hopefully lead me to a solution.
Look into the almost disposable bags sold for keeping frozen stuff frozen, or the promotional stadium seats. Also the pads sold for gardeners to kneel on. Also lots of packing material for electronics.
