In addition to being thinner, the Golden Threads paper is more see through. It will be easier to see where you are quilting using the Golden Threads paper. It goes a long way. A roll of Golden Threads paper is 20 yds (60 ft), the Parchment Paper I have is only 24 ft. It's not that much more when you take that into consideration. I don't care to mark directly on my quilts, so I find it is a worthy investment for me.
