I own a queen comforter and just change the duvet every season. I have a bird motif for the spring and a blue/white ticking stripe for the summer, but the plaid flannel is my favorite so I keep it from late fall through winter. Every year I post a photo of my bedroom and receive many questions of where things are from so I decided to link everything below for easy access.
Monogram Decal – Oxford design, center letter is 22″ high and outside letters are 12″.
Duvet Cover – Similar style from LL Bean. Same colors, small plaid. My duvet is LL Bean but the style is no longer carried.
White Pillow Shams: 26×26 Euro Size in Navy
Navy Anchor Pillow: Ralph Lauren find at Marshall’s.
Bed – Triple Raised Panel made of solid brown maple in coffee stain. Made by the Amish in Ohio, so there is no link online available.
I also love this bedroom I found on The Inspired Room:
I found this Pottery Barn duvet similar to the photo above. I’m tempted to get it, but I think it looks best if you have colored walls and not a dark navy like mine.
This Pottery Barn Duvet below is beautiful as well!
Lastly, this Land’s End flannel duvet is a nice alternative is you want one with a larger plaid:
