Step by step: how to sew baby harem pants

Cutting out

Step one: Download our free baby harem pants sewing pattern and print, then cut out the pattern.

Step two: From the main fabric, cut two pieces using the template for the front and back of the harem pants.

Step three: From the contrast fabric cut:

  • Waistband: 12x42cm (434x1612in) (cut with the stretch on the long side).
  • Leg cuffs: two pieces 12x18cm (434x718in) (cut with the stretch on the long side).

Stitching the main body

Step one: Place the front and back of the harem pants right side (RS) facing and pin together down both outside legs and all around the inside leg.

Step two: Sew together along the outside legs and inside curved leg.

Step three: Turn RS out and press. You won’t need to clip any curves as the knit fabric will stretch around the seam .

Making the waistband and cuffs

Step one: Take one of the leg cuffs and fold it in half lengthways RS facing. Pin then sew the two short ends together to create a fabric loop.

Step two: Finger press the seam open.

Step three: Fold the loop in half wrong sides (WS) together with seams matching to create
a double loop that is now 6cm (238in) deep.

Step four: Repeat this for the other leg cuff and the waistband.

Attaching the cuffs

Step one: Place one of the cuffs over the bottom of one leg, so that the raw edges of the cuff line up with the raw edges of the harem pants. Make sure the cuff seam is laying against the inside leg seam.

Step two: Pin together all the way around. You will need to stretch the cuff slightly to match the width of the pants leg.

Step three: Sew together then remove the pins and tuck the seam under.

Step four: Repeat this step for the other leg and cuff piece.

Attaching the waistband

Step one: Attach the waistband in the same way as the cuffs, but mark the quarter points on both the waistband and pants top edges to make them easier to pin. The waistband seam needs to be positioned in the centre of the back of the pants.

Step two: Pin together all the way around, matching these quarter points and stretching the waistband to fit as you go.

Step three: Stitch together as for the cuffs.
