I can't tell you how many times I have had these made up. You cannot go wrong with a monogrammed RL polo.
Anything from iomoi.  I especially love the lucite trays, but they have everything from coasters to carry- ons.
Often times I will incorporate a monogramed or personalized item into a job.  Jonathan Adler has a customizing option for pillows and rugs.
William Sonoma Home has cashmere blankets in wonderfully soft, assorted colors.
LOVE this brass table lamp from Roll and Hill.  It is perfect in a cozy office.
The ultimate in personalization is painting or using decal monograms in any room of your home.  I can see it used in a nursery, master bedroom, or really graphic and large as a focal point in a living room.  The application of this easy technique could really be a "wow" factor.
Sunny's  Good Time Paints has a plethora of options.
