Those strips look like separate layers that make up plywood. You’d use them to lay up eg. custom curved plywood structures for furniture. But I can’t figure out how to google for that without being shown loads of results for regular plywood sheets.
Hey Clem, I was thinking you could look into flooring, but that wouldn’t work because of the T&G, but your best bet would just be a 1-2mm veneer. There are plenty results on Google, depends on what species you want to use and the cost. Alternatively, you buy a standard sheet and create the veneers yourself.
Perhaps someone here has experience buying veneers.
