They are lined with thinsulate and are very fluffy. The color was perfect and the price was right for me, so I picked up a panel.
You can see the 2 layers of lining here. They make the pillows so comfy! Excuse the un-manicured fingers! I just measured out what I needed and made basic pillow covers. I used old throw pillows that I wasn't using anymore for the stuffing. I also have enough fabric left for 2 more pillows if I need some elsewhere!
Here is the finished product. I spent $20 on the curtain panel and used about half of it. The pillows I already had, so that comes out to about $5 a pillow. Not bad!
