These Hermes cushions are absolutely gorgeous and I do get asked about them an awful lot, the covers were purchased from Etsy and the insert cushions are duck feather which were purchased separately.
The cushions covers cost around £30 each they are not the silk ones its quite a thick material and the feather cushions were £10 each if i remember rightly.
I got mine around 7 months ago so you may still be able to get them!
I move these around the house an awful lot and usually they end up upstairs because my dogs seem to think that the cushions on the sofa are their beds!
The chanel book is from Amazon (still available at £12)
have a fabulous day!
