I’m fixing to make a new bench.  I have a good bit of 8/4 maple that I plan to rip into roughly 3 inch widths and and glue together on edge – pretty standard.  I’m still toying with the design including the width of the top, and may need more wood if I decide to go wider.  This brings me to my question: I have an 8/4 walnut board that I picked up cheap a while back owing to some significant sap wood (lighter) on portions.  Could I use this for a couple of strips in amongst the maple, or am I asking for trouble mixing these species in this way?  Anyone with experience with something like this out there?  Thanks in advance for any advice.
