I need to trace off the correct size so I set up my handy tracing table in the living room. I pieced the table together with two TV trays, an old hollow door that the spouse cut in half years ago, and two plastic storage containers (full of sock yarn, but that doesn’t matter). This raises the working surface to a perfect height. I don’t have to bend over, and as an added plus, it is right in front of the TV.
I don’t put the paper over the top of the pattern piece, but I put the pattern on the top held down by a weight. I use a fairly ‘wet’ pen like a Paper Mate Flair pen (my favorite) and draw right on the pattern. The ink soaks through to the paper. This only works with patterns printed on tissue-type paper. My patterns are not collector pieces so I don’t mind if I mark them up. If they were vintage patterns, of course I would carefully trace them without marking them.
