Get some cheap 1x1x6 walnut blanks and some maple veneer. On a bandsaw cut a scroll shape through the bank, top to bottom. Now soak a 1" strip of the veneer in hot water to make it more pliable. Once the veneer is easily bendable to the saw cut, clamp the pieces all together and let them dry. I used o let them sit for 2 days, then take them apart and sit for another day. Then glue the 2 parts of the blank back together with the veneer in between. Wait another day for the glue to dry.
Now clean up the blank so that it is back to about square, rotate the blank 90 degrees and repeat the above process. the end result is all 4 sides have a curve, scrolled or whatever design you cut in them.
Some personal preferences, use 2 or more layers of veneer, or as an example, a layer of maple, walnut and another maple. Or when cutting one side, make 2 cuts, so you have 3 pieces, and use 2 veneers. A tricky one, stack a maple and a walnut and cut through both at once. then repeat on the second cut and glue up.
Because of the excessive wait time. I preferred to do 4 or 6 at one time. When first starting this project make the saw cuts different so that you can replicate the ones you like the best. Sometimes simple is better.
