Sewing machine hemming techniques and hemming sewing machines   Tips for hemming clothes Method/Step 1 1. Cut a hemming strip, such as a 4 cm wide hemming strip, with a length of 80% of the collar circumference (generally, the length of the more elastic one is shorter. For my fabric, which has a good elasticity, I just use 80%. I heard a fabricator before. A friend said that she sometimes takes a little more than 70% of the collar circumference, and the elasticity is usually 80~85%. If the elasticity is not good, it is 90%. I usually take the two figures of 80% and 85%.) 2. Sew the hemming strip face to face into a circle 3. Facing the front of the hemming strip to the back of the garment piece, pull it evenly with the body and neckline and secure it with a beading needle. Method/Step 2 1. Make a circle around the collar, about 5mm wide 2. Turn the hemming strip over, then fold it in half to cover the neckline. In order to make it easier to see, I fixed it with a beading needle. 3. Carry one circle along the outermost edge of about 1~2mm. If you want it to be the same as the one you bought, you can carve it twice (note: if you have a good grasp of the sewing machine, you can do this. If the straight line is not very straight, just carve it in one direction) 4.Complete The above are the hemming techniques for ordinary sewing machines.
