The Slim Jim Trousers are classic casual style pants for boys or girls; slim and neat fitting in the hip and legs with elastic in the back waist, a front zip fly and standard jeans pockets on back and front. The pattern includes a knee length shorts option. PDF SEWING PATTERN: the pattern can be printed on a desk top printer using 8.5"x 11" / A4 size paper or Letter size if you are in the USA. The pattern file includes a very detailed sewing tutorial with step by step photos. The computer made digital pattern comes as a color coded, full size range nest with seam allowances included. Instructions for printing and assembling the pattern are included. All seam allowances and cutting instructions are marked on the pattern pieces. It is best to print out only the pattern pages and view the tutorial on your computer to zoom the photos. Please read the printing instructions on the Test Square page and the pattern assembly instructions on the Layout Plan page. BASIC SKILLS NECESSARY Experience: you will need to have advanced beginner to intermediate sewing skills to make the pants. Neat and accurate seaming is essential; one buttonhole is required and a zipper fly placket. A zipper foot attachment is necessary to sew in the zip. Overlocking is best to finish the seams; alternately use the zigzag stitch on your plain machine. Follow the sewing tutorial closely to be sure to sew everything in the correct sequence. Read through the tutorial before starting. SIZING / FINISHED MEASUREMENTS Sizes: 2, 3, 4, 5, 6, 7, 8, 10, 12 to fit children 2 to 12 years old.
