For great printed sheets I often go to Homegoods and pick up something from Ralph Lauren. They have such a wide variety of prints and I also really like the crispness of the cotton.
I also really like to add a Euro sham to a bed that is in a coordinating print. At times I have them custom made like I did with my One Room Challenge below using this great fabric from Michael Smith for Jasper:
While super luxurious they do not come cheap. BUT.....they have a white sale twice a year which is currently happening. I have been adding things to my virtual cart all week. I haven't pulled the trigger on anything yet but I am certainly tempted to order a couple of shams....or just a boudoir. Take a look at some of the rooms below that feature D. Porthault bedding.
