We did a post on this about a year and a half ago but the pictures were not very big. I thought I would do an updated version of my own jeans that I have hemmed using the original hem method. It’s really easy, anyone can do it even if you are not a master with the sewing machine.
* Be sure to only do this method on skinny or straight jeans as it doesn’t work on bootcut or flares due to the fabric not being the same width around the ankle area.
All you need to hem your jeans is: Tape measure, pins/safety pins, needle & thread (or sewing machine), iron and of course your jeans.
1) Lie your jeans out on a flat surface and measure the inseam. Note down how much you want to take off of the length and half it. Always remember not to include the actual hem itself in your measurements as you will not be taking any off the hem. It’s easier to do one leg at a time so you wont have to undo both if any mistakes are made.
2) Fold the hem of your jeans inside out to the correct length you have measured, in the example this would be measuring 1″ of the fold as I am taking off 2″ in total (do not include the hem itself in the measurement). Re measure from the crotch to just under the original hem that has been folded outwards and make sure it is your perfect length (minus the hem width itself). Do not measure right to the end of the jeans where the fold is, your jeans will not be this long as you are not sewing at the bottom of the fold. You might want to get an iron and make sure that the fold is flattened down, I personally use an old hair straightener quickly (be careful not to press it down for a long time so you don’t burn the denim) as it’s easier to put the plates each side and flatten it. Make sure the seams on the left and right side of the leg match up correctly to the hem once it’s folded. Now put some pins in all the way around to hold your fold in place.
3) Now you are going to sew all the way around the hem. I have drawn some pink stitch marks on the image so you can see where to sew. You need to sew right under the hem, not on the actual hem itself. Sew just under it so you are only going through 2 pieces of denim (the folded bit). You can either do this by hand with a simple forward stitch secured at both ends or with a sewing machine. I personally do it by hand as it’s easier for me and it’s easier if you wish to let the hem down. It doesn’t matter which colour thread you use or how neat your sewing is as the stitching will be on the inside of the jeans and invisible on the outside. Be sure not to sew the leg opening together so opening ends up closed.
