I needed some paper to trace out a Burda WOF pattern.
I work in a bakery, and it occurred to me that the paper sheets we use to line the baking pans with would work. The paper sheets are large, about 18" x 26" so they are large enough for most of my pattern pieces. I can tape 2 together for longer ones, like dresses or longer skirts.
It's basically vegetable parchment, and very easy to see thru.
I don't know what a bakery would charge for it, but I got it almost free since I work there.
In a pinch you could probably buy some from your local grocery store bakery. Just ask for paper pan liners.
It works great!
