PDF sewing pattern for boys casual trousers -- Slim Jim Pants

The Slim Jims 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.

Sizes: 2, 3, 4, 5, 6, 7, 8, 10, 12 to fit children 2 to 12 years old. Always check the size chart for your correct size, waist and height measurements are the best guide.

Fabrics: Medium weight woven fabrics are the most suitable: linen, cotton drill, denim, corduroy, wool and similar fabrics. Stretch denim and drill are ideal for these pants. Choose fabrics that are not too thick.

Experience: advanced beginner to intermediate. 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.

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.
