I have a roll of what they call vellum for the large printers that are used for printing engineering drawings. It is 36inches wide, and is fairly easy to see through to trace the pattern. It saves a lot of time rather than having to tape pieces of tissue paper together and it holds up better if you want to use it again. I have always hated the tissue paper patterns because I like to use a pattern more than once (with modifications,) and either I am too rough on the patterns for the paper is too wimpy.
