Sycamore, if quarter sawn, can have a "lacewood"
look (third image - lower right on this page - watch
the line wrap)

Sawn "through and through" it can be pretty boring - the
grain being pretty fine and the wood pretty pale. Freshly
felled and cut, the wood can look salmon colored all the
way to flat out orange. Unfortunately most of that color
goes away after drying.

It isn't the most stabile wood so wood movement accomodation
must be made. The interlocking grain, which gives the lacewood
look, can be a bit tricky to work without tear out. Sharp tools
minimize tearout.

In the hands of a good sawyer, your sycamore can produce some
really pretty boards that would make some nice stuff.

Now if you cut any elm ...
