Attaching wall panels

[Patator100]

Hello

I m building wall panels with 2inch hr foam, 1/2 plywood and 600g/m2 marine vinyl leather. 80cmx52cm (31inchx20). The 24 Panels will probably be around 4kg / 8 lb each.
I m looking at the cheapest and easiest way to attach them to my walls :
- French cleats (96 to install) : around 120usd
- neodymium magnet : around 100usd
- Velcro : not sure it will be resistant enough

Do you have any experience / suggestion to help me in my choice ?
Thanks

While you have given good information regarding what you want to attach you need to also detail what they will be attaching to.

Hi. Drywall
i will go for button-fix clips. The easiest and cheapest solution in my eyes
