How to Sew Lounge or Pajama Pants

Gather supplies to stitch lounge pants or pajama pants, with machine, iron, scissors, measuring tape, pins, and thread (contrasting or matching), plus prewashed fabric and yardage by size from website.

Prepare fabric by washing, drying, and ironing to prevent shrinking, then fold to align salvage and cut line, cutting on a double layer for two front and two back pieces.

Learn to take precise measurements for waistband casings and pant hems using a seam gauge, easy him, and a tape measure, with marking and pinning techniques.

Choose the regular or large drapery easy hem; the large handles up to 18 inches across. Iron along the marked edge, then fuse with feasible webbing and sew for security.

Open the pattern in Adobe Reader, use the layers panel to hide other sizes, and print at actual size on 8.5×11 or A4 paper for the selected pattern.

Measure the printed pattern against a 2x2 square at regular size with no trim. Align the overlap lines and triangles to form a diamond, then tape pages together.

Tape the pdf pattern pieces together, then cut along dash or solid lines for the waistband, pocket, pants back, and pants front, marking overlaps to ease layout on fabric.

Measure the inseam from crotch tip to hem using a reference pair. Add seam allowance to pattern, then mark seven inches up from the hem on front and back.

Pin the pattern to fabric, smooth it, and cut along the edge with long strokes, using pattern weights when needed for lounge or pajama pants.

Mark the front pattern pieces with fabric chalk on the inside and label them, then remove pins, fold fabric with right side aligned, and ensure front and back markings match.

Align the front and back fabric pieces right sides together at the crotch, pin with a 5/8 inch seam allowance, then sew the crotch areas on the machine.

practice five eighths seam allowance while sewing the crotch of lounge pants with a straight stitch at 2.5, back stitches, alignment pins, and fabric guided through the machine.

Clip the curves at the crotch to help the fabric lay flat and fit better; use scissors, pink shears, or painting shears, and press the seam open.

Finger-press crotch seam open, then press with an iron along curve, left to left and right to right, so fabric sits flat; reclip if it won’t press open.

Prepare a clean waistband for lounge pants by anchoring the front and back, marking for elastic insertion, and finishing edges with a serger or zigzag.

Form the casing crease with an inch-and-a-half guide, use the straight or curved edge to keep accuracy, then pin, press with the iron, and sew the front and back panels.

Align front and back pant panels with right sides together at the waistband, pin, sew the side seams at 5/8 inch, and finish edge with a serger or pinking shears.

Finish the leg hems by folding a 1-inch hem, pressing it in place, then stitch so the edge stays flat for the elastic through the casing.

Pin the crotch seam and align the center sections. Sew the inseam with right sides together from one side to the other.

Line up the 5/8 inch seam and sew the waistband and leg hems with needle-down back-stitch, guiding gently. Use start-stop pins, fold and press, then pull threads to the back.

Learn to insert a non-roll elastic into the waistband casing, measure the waist, and close the opening using zigzag stitching and careful alignment to prevent twisting.
