  • Sewing machine

How much fabric do you need for your DIY boiler suit pattern?

Your fabric width determines how much fabric you will need. The sizes and amount of fabric required are based on an appropriate fabric width of 140-150cm. You can find the size and amount required by checking the table below. In the event that your fabric has a different width or design (i.e. stripes, plaids etc), you'll need to adjust the placement of the pieces.

Check your contraction!

A must-read! The contraction of the fabric you choose should be checked before cutting. In order to accomplish this, iron steam the raw material at its maximum recommended temperature. As a result, your finished garment will remain true to its size after it has been washed for the first time. Consider buying 5% more than your project requires to account for shrinkage.

How to Sew It

Sewing A Boiler Suit Pattern- Instructions

Once everything is set up, we can begin sewing. The instructions included with our pattern are easy to follow.

Here we go!

Sewing The Bodice

  • Apply fusible interlining on the wrong side of the flaps, the cuffs, the collars and facings
  • Take the flap pieces and pin them together, 2 by 2, right sides together. Sew around four sides, leaving the top edge open. Press. fig 1
  • Turn the flap through to the right side. Press. Make sure the under flap does not show on the right side. Top-stitch the flap around the four sides. Overlock the top edge of the flap
  • Position the flaps on the right side of the front pieces placed upside down and sew at 0.5 cm according to the markings on the pattern. Then fold the flaps into the natural position and topstitch at 1 cm. fig 2
  • Fold the 2 pleats at the back of the bodice towards the sides and sew the raw edge at 0.5 cm to secure it. fig 3
  • Sew the yoke to the back piece, right sides together, using a 1 cm seam allowance. Neaten the edge with an overlock stitch and press. fig 4
  • Top-stitch the yoke seam from the right side, at 0.5cm from the edge, catching the seam allowance also.
  • Sew the front and back pieces together at the shoulder seams using a 1 seam allowance. Press the seam open and neaten the edges with an overlock stitch. fig 5
  • Sew the side seams using a 1 cm seam allowance. Press the seam open and overlock.
  • Pin the waistband pieces on the bottom of the bodice, placing the bodice between the 2 parts of the waistband, taking care to meet the notches. Sew at 1 cm and press the seam open. fig 6
  • Sew at 0.5 cm the 2 parts of the waistband at the bottom.
  • Insert the elastic into the channel, bring the ends of the elastic up to 1 cm from the edges and fix it with a seam next to the notches on the cord from the front, so that in the 9 cm from the middle of the face to the notches the elastic should be relaxed and on the large portion of the cord, it should wrinkle. fig 7

Sewing the pants

  • On the pocket opening of the front trousers (right side), apply a fusible reinforcement tape so that it does not stretch (you can also use a stripe of interlining).
  • Attach the pocket to the front pants, right sides together and sew at 1 cm. Press the seam. fig 8
  • Top-stitch right side of the pocket, at 0.5 cm from the seam, catching the seam allowance in the seam. fig 9
  • Sew the bottom of the pocket and overlock the seam.
  • Secure the pocket on the top of the pants and in the side seam with a stitch at 0.5 cm. fig 10
  • Overlock the center front raw edges.
  • Sew the center front seam, starting from the slit down. Press the seam open. fig 11
  • Place the back pants pieces, right sides together, and sew the center back seam, using a 1 cm seam allowance. Press the seam open and neaten with an overlock stitch.
  • Pin the front and back pants, right sides together, and sew the side seams, taking care to meet the notches. Press the seam open and neaten with an overlock stitch.
  • Repeat with the inner seam of the pants.
  • Double-turn up the hem of the pants (2.5 + 2.5 cm) and sew at the edge. fig 12
  • Sew the pants on the bottom of the waistband, right sides together, taking care to match the notches. Overlock the seam allowance and press the seam.

Sewing the sleeve vent placket

  • Take the sleeve vent piece and mark the pattern lines with chalk. fig 13
  • Place the placket to the shirt sleeve, right side of the placket to the wrong side of the sleeve, aligning the middle mark with the sleeve's vent mark. Sew a rectangular box, joining the tailor's tacks together. Make sure the rows of stitches are parallel. fig 14
  • Snip though the placket and sleeve straight down the center, between the rows of seams. Snip into the corners of the rectangle, being careful not to pass the seam.fig 15
  • Fold back the long edge of the shorter side of the placket. Place the folded edge on top of the sewn line and pin in place. Sew the folded edge with a 1 mm seam allowance. Stop the sewing at the top of the gap. fig 16
  • Fold the other side of the placket across the shorter side. Press under the long edge. Fold back so that the pressed-under edge is on the sewn line. Pin in place. Fold under the top pointed end, following the cut edge, and press. fig 17
  • Sew the long folded edge in place. Make sure the underside of the placket is not caught by the stitches. Continue sewing around the top. fig 18
