Nähanleitung Schmetterlingsshirt Antonia

Sewing instructions butterfly shirt Antonia

The Antonia T-shirt is easy to sew and therefore belongs in our " I'm still learning " category. The sophisticated cut gives the shirt a special look with a hippie character. The ruffle on the side covers the upper arm like a sleeve. The hem is gathered with the help of a narrow elastic band and thus ensures a good fit.

Length at center back = 53 - 59 cm

In these instructions, Antonia was sewn from a viscose fabric.

Cut out the pattern pieces from your outer fabric and interlining. Lay the fabric right side up. Lay the selvedges parallel to the center so that you can fold the front, back, arm bands, lining at the back and front. The pattern pieces should all be face up. Always align the grain arrow on all pieces in the same direction and parallel to the selvage of the fabric. Transfer all the notches from the pattern through a 3mm long incision with scissors or chalk. Pinch the seam allowance in the fold of the fabric because this is always a center. Markings define positions of dart ends, pocket positions, etc. Transfer these either with chalk or pins. It is best to first roughly cut all outer fabric parts that are completely covered with an interlining. After you have fixed the insert, cut it out exactly. There is also a video about gluing and fixing pattern pieces here.

Sewing instructions:

You will need a sewing machine to sew this shirt.

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!

Begin your sewing work with the facings at the front and back. Place them right sides together and close the shoulder seam. Iron the seam allowances apart.

Then neaten the outer cut edge all around...

... iron them down 1cm and stitch the seam allowance all the way around.

Now sew the shoulder seams of the front and back pieces right sides together, neaten the seam allowances and iron them to the back.

Place the finished facing right sides together in the prepared neckline and sew the two together. Before ironing, pinch the seam allowances in the curve.

Fold the neckline facing inwards and stitch it all the way around at an even distance from the neckline. Pin the slip in place with pins so nothing can slip while sewing.

The arm panel gets an auxiliary seam to secure the route, since the thread run is slanted and the woven fabric stretches faster there. You can prevent this with a large-stitch auxiliary seam.

Iron in and around the outer curve 2x 0.7cm and topstitch the edge.

Now sew the facing to the front and back pieces, right sides together. Make sure that you iron and iron the hem according to the pattern beforehand and that you only sew the panel up to the first ironing edge.

You prepare the side parts by ironing in and around the upper short section. This is later part of the lower armhole. You can also iron the hems in and out according to the pattern. You'll put a rubber band in there later.

Sew the side pieces onto the panel right sides together up to the top knot. Now neaten the entire stretch together with the entire armhole in one go. Iron the seam allowances to the back or to the front.

Stitch through the prepared hem of the front and back sections.

Cut the rubber band to the right length and stitch it to the dividing seams. Fold the hem of the side panels around the elastic band and stitch it close to the edge.

Here you can see how the elastic band in the side parts looks like.
