Sweatpants and hoodies are now an integral part of our wardrobe, we all love it comfortable and casual. Our Ike onesie tops these needs, has a loose and casual cut with plenty of freedom of movement to really chill on the sofa. Designed as a men's overall, there are just as many lovers of this cozy one-piece suit. We have added a dividing seam between the upper and lower part and with the additional lines drawn in, the overall can be easily shortened or lengthened to the corresponding body size.

Length center back neckline to hem = 153 - 168 cm

In this pattern, Ike was sewn from a soft sweatshirt with a reverse side.

Required material:

We recommend a thicker jersey or sweat fabric

Cut out the pattern pieces from your outer fabric. Lay the fabric right side up. The pattern pieces should all be face up. Always align the grain arrow on all pieces in the same direction and parallel to the selvedge of the fabric. Transfer all the notches from the pattern through a 3mm long incision with scissors or chalk. Markings define positions of dart ends, pocket positions, etc. Transfer these either with chalk or pins.

  • 2x front part in opposite directions
  • 2x wedge in opposite directions

  • 2x hood in opposite
  • 2x front pocket in opposite directions
  • 2x sleeves in opposite directions

Sewing instructions:

To sew this overall you will need a sewing machine and an overlock sewing machine, alternatively you can use the zigzag stitch on your sewing machine to finish the raw edges.

Be sure to use a jersey needle and use a stretch stitch, i.e. if you are sewing with a home sewing machine you should use either a zigzag stitch or the tripartite elastic stitch and then all seam allowances again with a zigzag stitch or another appropriate stitch neaten so they don't fray. In addition to the description, the colorful lines in the pictures show you where a seam needs to be sewn or something to be glued.
When sewing, pay attention to the seam allowance included in the pattern. Seam allowances that are not specially marked are 1 cm wide!
Happy sewing!

Note that we have already closed the dividing seams of the front and back parts, neatened them together and ironed the seam allowances down.

Clean up the lower long side of the pocket panel before processing with the kangaroo pocket. Now place the panel, right sides together, on the pocket opening of the front pocket and sew both together.

Then fold the facing inwards so that a piping is visible and stitch it through from the right in the shadow of the seam.

Now you clean up all the raw edges of the kangaroo bag all around.

Iron the trimmed seam allowances according to the pattern.

Lay the bag parts according to the markings in the pattern on your front center of the front parts and stitch them up just under the edge and 0.7 cm wide.

Take the back pieces and close the center back, right sides together. Make sure to leave an inch open at the bottom for working the wedge. The center back is finished later with the seat seam in one go.

Now put the gusset in its correct position on the back pieces and neaten the seam allowances together.

The back pocket is also trimmed all around...

... and is then ironed. Stitch through the pocket opening.

Fix both pockets on the back part at the markings in the cut with a quilting just under the edge and at 0.7 cm.

Sew the inside leg seam of the front and back pieces to the front pieces in one go with the other side of the gusset, right sides together. Here you neaten the seam allowances together.

Now we come to the seat seam. You close this, right sides together, starting from the last stitch on the center back and ending at the snap in the center front. The snap marks the end of your zipper. The seam allowances of the seat seam and the entire back center up to the neckline are finished in one go.

Close the shoulders, right sides together, and neaten the seam allowances together. Then iron everything backwards.

Now you take the hood cuts and lay both, right sides together, on top of each other and stitch the center back together. Neaten the seam allowances together and iron them to the wrong side of the body.

You then sew your prepared hood into the entire neck hole. You neaten the seam allowances together.

Before working on the zipper, neaten your seam allowances in the center front: starting from the bottom, going over the hood, to the other side, further down and ending there. Only now can you put your zipper in place and topstitch just under the edge and 0.7cm wide.

When the zipper is finished, you can finally close your side seams, right sides together, finish them together and iron them to the back.

For the sleeve hems you have cut your cuffs from rib or the outer fabric. Sew them together, right sides facing, and iron the seam allowances apart.

Then turn the cuff right side out in the fold and secure both layers with an auxiliary seam the width of a quilting foot.

Prepare the sleeves by sewing them together, right sides facing, overcasting and ironing the seam allowance to the back. Pay attention to the seam allowances in the pattern.

Place the cuff, right sides together, on the hem of the sleeve, stitch both together and neaten the seam allowances.

Now sew the prepared sleeves into the correct armhole and neaten the seam allowances, paying attention to the notches.

We pull an elastic band into the hem. Cut the elastic to the correct ankle circumference and close it in a round.

Clean up the hems of the legs all around and iron them according to the pattern.

Finally, place the elastic in the pressed-up hem and stitch the hem all around
