Discovered transparencies. They work really well as tracing paper, but a laser would still be far faster and easier on your fingers. Requires laser printing rather than inkjet for best results, though variants for both printing methods exist.
– They’re completely water resistant
– The warping is pretty easy to work with
– Ideal for lining up and can use a sketch rather than finished line art
– tape removes a small amount of ink but not enough to matter
– highly preservable. can probably get 6-10 traces out of 1 sheet
