stitch a pair of trousers
1 Download and print the pattern. Take your hip measurement and divide it by two, then add 15cm. Where the pattern asks you to extend to your hip measurement, this line should equal this figure. Gauge your crotch by measuring a pair of trousers that fit you comfortably, from the centre base up to the waistband. If you need extra length, cut through the line indicated on the pattern and extend it to the measurement that suits you. Repeat for both the front and back pieces. For a loose fit, make sure this isn’t too tight.
2 Lay the patterns on your fabric with the extensions added to fit your measurements. Draw a line with pencil or chalk joining the back waist to the front. This line will be slightly angled as the front crotch is shorter than the back. Extend the leg seams down far enough to match your leg measurement. To take this, measure from your inside leg down to the floor, and add 3cm for the hem. Draw a line across the base of the trouser leg.
3 If the pattern piece fits onto a double section of fabric, cut them out together. Alternatively, if the fabric is too narrow cut a single leg out, then turn the pattern over onto another piece of fabric, making a pair.
4 Match the two front trousers together and stitch with a 1.5cm seam allowance from the crotch up to the waist edge. Repeat the process on the back trouser pieces and neaten the seams together with a zig zag stitch or overlocker.
5 Match the base of the front and back crotch seams together and down the inside legs to the hems. Pin and stitch all seams together and neaten with a zig zag stitch or overlocker. Using a strip of bias binding 1cm longer than your waist measurement, join the two ends together with a 5mm seam allowance.
6 Open out one of the folds and pin this, with right sides facing, to the top of the trousers and stitch along the fold line. Fold the bias binding inside the trousers and edge stitch around the other folded edge, creating a channel. Unpick a few stitches in the centre front part of the channel and thread through a length of piping cord or ribbon. Press 1cm up at the hems of the trousers and a further 2cm. Edge stitch the hem in place to finish.
