I do the coved boxes in groups of 10 or more. Helps make some of the steps a little more efficient but the wood determines size so they are all a little different in length-height and width. I also change the top and bottom profiles-the feet and the lid. Great way to showcase those small wild pieces of wood you have tucked away. I love using Walnut Big leaf Maple and cherry- we are so lucky to have these woods in abundant supply. All pieces of BLM are guitar blank rejects. I buy them by the pallet. Pretty cheap wood for what you get.
If you get sick of boxes tell me- I build a lot of them.
