For this week just study for your exam, my suggestion is draft a pants front and back only from memory then check the book to see how you fared. You will be asked to draft and label the lines, add the measurements that will be given in class along with a legend much like the skirts. There will be questions as well so know your fixed measurements, terminology etc. You all aced the skirts exam I'm sure you will do the same for pants.
After the exam we will be doing some seam finishes so please bring in about 12 muslin rectangles measuring 40 cm X 25 cm, your sewing machines etc.
