How to sew a sweatshirt

Draft a pattern

 To kick off this DIY, Trace a sweatshirt you already have to create a pattern. Make sure to trace both a front and back neckline for your pattern piece. 

Trace the sleeve

Once you have the bodice pattern piece, you can trace the sleeves. 

Pin on the pattern piece

Cut out the fabric 

Next, take the pattern piece and pin it onto a piece of fabric. 

Add seam allowance

 Take a piece of chalk and add seam allowance around the pattern piece. 

Cut the neckline

 Once you have your back piece cut out, trim the neckline on the pattern piece and repeat the same for the front bodice piece. 

Sew a sweatshirt

Next, fold your fabric and cut the sleeve on the fold. 

Sew the shoulder seams

Attach the bodice pieces 

Time to assemble the sweatshirt Place your front and back pieces, right sides together, and sew along the shoulder seams. 

Make a sweatshirt

Trim the shoulder seam and then zig-zag stitch over the seam. 

Measure the neckline

Add a neckband 

Grab a measuring tape and measure around your neckline. Multiply that measurement by 0.8. 

Cut a strip of fabric

 Next, cut a strip of fabric according to your neckline measurement multiplied by 0.8 and sew the ends together. 

Make a notch in the band

Make a small notch in the center front of the neckband. Match the center notch with the seam at the back and then notch each side of the band. 

Notch the neckline

Then, notch the center front and center back of the neckline. 

Sew on the neckband

 Fold the neckband in half and match up the notches on the band with the notches on the neckline. Sew the neckband in place. While you are sewing, stretch the neckband to fit.

Once your neckband is sewed on, grab a pair of scissors and trim around the edges. Then sew a zig-zag stitch around the neckline. 

Press the neckline

To get a neat and clean neckline, press it using your iron. 

Match the pieces

Attach the sleeves 

Next, it’s time to attach the sleeves. Match the center of the sleeve with the shoulder seam and sew all along the armhole. Then go ahead and sew the sides of the sweatshirt together and the sleeves closed. 

Add cuffs

 Cut two strips of fabric to be used as cuffs for your sleeves. Make sure that when folded they match up perfectly with your sleeve. Once you have the right size, sew the two ends of the cuff together. 

Match up the two seams

 Fold the cuff in half and place it over the sleeve, matching the seams. Then sew the cuff all the way around, attaching it to the sleeve. Just as you did for the neckline, trim the edges and then sew a zig-zag stitch. 

Fold the bottom

Hem the sweatshirt 

To hem the bottom of the sweatshirt, fold the bottom inward and pin the fold in place. 

Sew the fold

 Then sew the hem in place.
