I have decided to make several jewelry boxes for family members. Although they will be basically the same size, I want to incorporate different wood types. In other words, the boxes will not be strictly walnut, cherry, oak or cedar. I have made some drink coasters using three of these together and it looked fine. But they were small 3 1/2 by 3 1/2 and not really complicated. My concern is if I glue these types together into approximate 20-inch boards are there any issues that may come into play that I am not aware of? Maybe be a dumb question but I don't know. Cedar only for the inside btw.
