Can you tell me what this is?
 

I found this roll of paper in my sewing room. I have no idea what it is for, or where I got it from. I am not even sure it is sewing/quilting related.
It is a roll of paper that was still sealed up in the white plastic bag. The roll is 8.5 inches long and 2 inches in diameter.
The paper is not exactly glossy, but smoother than regular paper. It feels about the same on either side of the paper.
Can anyone tell me what it is and what it is used for? I feel it must have a specific purpose!

Back in the day, old fashioned fax machines used to use paper on rolls like that.

It could be used to create custom longarm designs. Do you have a longarm? It could also be used to trace applique or paper pieced patterns, but would be a little klunky for paper piecing. It's too thick for the the Carol Doak type, and too rolly for English paper piecing.

I was thinking fax paper also. Take a small corner off and iron it. If it turns black, it's thermal paper, which is/was used in most fax machines.

I was thinking "fax paper"

Perhaps you got it to make planned crazy quilts onto and then pull the paper off the back? Or maybe paper piecing? Planning quilting designs? Or to use to make pattern pieces when making a pattern for say a round table topper? If you are making something you don't want to cut up the pattern, it would work great! Like those stretch and sew patterns you trace off from multi-sized patterns.

I could have used this yesterday... LOL!

were you ever planning on string or crumb quilting? I also think it's fax paper, but works for foundations.

Is it stabilizer?
