Galley upper cabinets

I carefully cut the upper cabinet doors so the wood grain would continue from one door to the other. Using 5/8 inch Baltic birch 10 ply cabinet grade plywood. I found a supplier of 5x5 sheets of 5/8 for 20.00 a sheet. I used it for everything except drawer boxeswhich were 1/2 and cabinet back inside panels which were 1/4 inch. I will use 1/4 for the upper walls to reduce weight. All other walls with be covered in comercial cloth and insulation layers to finish.
