Pattern Tracing Paper

I had been debating what kind of pattern paper to purchase for drafting and tracing patterns. In patternmaking class, we just used marker paper, the kind that has the inch-grid on it. But I wanted something that I could actually baste or sew together. After reading this post from Amy, I thought that I would buy a roll of Swedish tracing paper. But it was sort of expensive. Then I started reading this discussion forum and this one too on patternreview.com about soil separator fabric. It's created by a company called Carriff and is now offered on their website as sewing fabric. A 48-inch by 300-foot roll was so economical at only $36 that I had to buy it. I'll be using it this weekend!
