Etsy sells the chunky cable knit throw/blanket. I would also use them for the pillows. If you don't see what you want you can contact the vendor and have them make it for you. Looks like you'll need two white cotton euro shams/pillows, two velvet shams to match the cable knit, a round rouched velvet pillow, and a white quilted coverlet. The rest look like sheets to stage the bed. Most of these items are basic and should be easy to find.

I think those might be jersey sheets, given the way they're hanging.

Target sells the jersey knit sheets.
