All it took was some ribbon and Heat and Bond...
and after ironing, I ran the ribbon through the sewing machine to be sure it will hold up in the washer and dryer.
For the rest of the bedroom, I ordered this striped duvet cover on sale from West Elm last spring (it's no longer available)...
and this bed frame from Cymax. I plan on making this beautiful headboard from West Elm myself. It retails for $499 but I hope I can make one for under $100. Wish me luck!
