If you provide no information, how the hell do expect anyone to give you advice? We have no clue what you like, the decor you may want to match, etc.
So, I'll say: Wrap the beam in sisal rope. It looks great! If you don't like that, maybe consider painting it taupe?
Or, you could always box it in with cedar...
Or just paint it yelow and be done...
Attractive is subjective. Tom
I once encased an 8' lower section of a cresote telephone pole with western red cedar. The pole presented a nasty problem for the unknowing children catching the school bus at this site. I adorned the octagonal casing, top and bottom, with simple moldings/dressing, as if it were a porch/veranda column. The casing is in 2 halves, latched together and easily removable, for whenever any utility workman needs to climb the pole. It has since weathered nicely and is still very functional after 10+ years. Hence, whatever suits your scenario.
