That's not good, is it possible to get a sheet of veneer 24'' by 48''? The Mahogany veneer I've seen so far is no where near 24'' wide.
You'll struggle to find a 24" wide leaf, but that's not a problem, just joint a book matched pair of narrower leaves to make your wider piece. Dead easy with hide glue (just overlap and trim), trickier with PVA or UF glue where you have to joint it
before laying, but if you have a bit of a practise before the real thing it's not too difficult.
The thing that's hardest about pre-jointing veneer is trusting the process, at first it all looks so implausible, but it really does work! You sandwich the two jointing edges (either together or separately) between two sheets of 15mm or 18mm MDF that have fairly straight edges. You position the veneer so it's poking out by just one or two mill, with the edges of the MDF exactly aligned, you cramp it all down to your (reasonably flat) bench top (works best if you have a removable tool well so you can cramp from the rear). Then you run your plane on its side with a finely set iron along the veneer edge. Personally I aim to produce a sprung joint even with 0.6mm commercial veneer, so I'll make stopped shavings until the plane no longer cuts, then I'll make one or two through shavings. After that you tape up the joint on the glue side, open the joint like a hinge and run in a minute bead of PVA, then close up the joint and tape the face side. After half an hour you remove the tape on the glue side and lay the veneer. Do a small practise piece first and you'll soon be churning 'em out like a champ!
Good luck!
