HOW-TO-DRAFT-THE-SLACKS-PATTERN-pattern-1

HOW TO DRAFT THE SLACKS PATTERN pattern 1) A to B – Equals side length measurement. A to C – Equals 6-3/4” for size 12 6-7/8” for size 14 7” for size 16 and up C to D – Equals 1/4 of hip measurements plus 3/4″ for ease. Square this line across at C. C to E – Same length as C to D. Extend line D-C to E; then pivoting at D, draw an arc line above E. A to F – Equals crotch depth measurement plus 1” for ease.

Mark point F on line A-B. G to H – Equals hipline D-E. Draw line through F, parallel to hipline D-E. G to I – Square this line up at G through D, making this line 1/2″ less than A to F. H to J – Equals 1/2 of line F to H.

Extend line G-H to J. H to K – Equals 1/2 of line H to J. K to L – Equals line G-I (center front) plus 2” for center back line. Draw this line from K to L touching the outer most curve of arc line.

G to M – Equals length from K to J. G to N – Equals 1-1/2”. Draw a diagonal line; then draw a curved line from D to M through N. K to O – Equals 1-1/4”. Draw a curved line through O. G to P – Equals length F to B. Square a line down at G. K to Q – Equals length F to B. Square a line down at K. P to Q – Connect for lower edge. P to R – Equals 1/2 of line P to D. R to S – Square a line across at R for knee line; then draw slightly curved lines from M to R and J to S for inner leg seam.

B to T – Equals 1” T to C – Connect. 2) Draw waistline slightly curved from I to A to L. Reduce waistline to fit 1/2 of waist measure. First make part of reduction at sides and center front. Then make a dart in back and a pleat in front as follows: C to U – Equals 1/2 of C to E. L to V – Equals 1/2 of back waistline; then draw a V-shaped dart, 6” long. D to W – Equals 1/2 of D to C. I to X – Equals D to W; then draw a V-shaped dart. 3) For crease lines on front and back, divide the knee and lower lines in half; then draw crease lines from bottom to hipline. For waistline, make a double band 1-1/2” wide finished and the length of waist measure plus 3/4″ extension for left side opening.

To complete the pattern, allow for seams and hem. Make corresponding notches.

HOW TO TAKE MEASUREMENTS WAIST – Take snug measurement. HIP – 7” below waistline. CROTCH DEPTH – From waist to chair. SIDE LENGTH – From

waist to ankle.
