Following the interest in my post about using industrial patternmaking card, here's another tutorial to answer a question a few people have asked.... This is how to trace multi-sized commercial patterns to cardboard!
1. I really can't stand tissue paper patterns. I photocopy them (on my poor little overworked multi-function printer). I use the window as a lightbox to align the pattern pieces while I stick them together. You can skip this stage and simply use spray adhesive on the original tissue paper pattern to stick it to card (I used to do that in the days before multi-function printers!!).***Edited to add - Check first that your photocopier doesn't alter the original size of the pattern (mine doesn't).2. Using a glue-stick or spray adhesive, stick the paper pattern to some patterncard.

3. Cut out the card, following the outside line (no matter which size it is). This is your pattern template.
4. Trace around the cardboard template onto another piece of patterncard.
5. Use a tracing wheel to follow any necessary lines in the pattern that are not on the outside edge of the template. A good spiky patternmaker's wheel is the best thing for this, or you may be able to use carbon paper and a (slightly less-dangerous) dressmaker's wheel.

6. Lift up the template and trace over the line of dots that the tracing wheel has made on your new pattern piece. A patternmaking ruler is great for drawing smooth body-shaped curves (or long, straight lines).
7. Transfer all the pattern markings through to the new pattern piece. For grainlines or other straight line markings, draw a line straight over the template and onto the base cardboard. Lift the template and rule the line through on the pattern piece.
8. Mark any dot placement through to the new pattern with a small hole (use a pin or tailors awl). You can then punch these holes out on the new pattern, but the template won't be damaged.
9. Trim away the template so that the next size down is the outside edge.
10. Repeat the whole process for tracing off each new pattern size, until you reach the smallest size. You can use the original template as the smallest pattern piece.

11. Punch holes in the patterns so that you can hang them up.
12. You can use a proper pattern hook or just use a loop of string.... 
13. Ta-Dahhhhh! Lovely cardboard patterns that you can TRACE onto your fabric. No need for pins!!!
