Grammahunt. I have one of the4X8 sheets and covered with flannel and it works wonderfully. I seldom need more space. The other side of your "argument" is that this will last for years and years. I inherited my from my sister-in-law who was a super quilter. The panel was old when I got it 10 years ago. It is at least 20 years old and still working well, has not broken down and is easy to move from place to place if needed. I would pass up on some other quilting materials, fabric, books or what ever and save the $$ for the insulation. For me... it would be worth it!
