How To Upcycle Jeans for Sewing Projects: 11 Tips

Using old jeans is a great way to save money on fabric while keeping old clothing out of the landfill. Here are 11 tips for upcycling jeans for sewing projects.

1) Collect Your Jeans

When working with denim for scrappy projects, you’ll want to have a variety of colors that you can use like different fabrics. If you can’t find the colors, fiber content, or sizes you need in your own pile of old jeans, Stephanie from Swoodson Says reminds you that “people always have old jeans laying around. Ask friends & family to save some for you!”

2) Check Your Labels

When sorting out jeans to use for your project, Heather from Heather Handmade says, “The more spandex there is in the denim the weaker it is. You’ll have better luck with non-stretch denim!”

3) Prep Your Denim

Before you start cutting up those old jeans, I recommend machine washing in hot water and drying on a high heat setting. This will get your jeans as shrunk down as possible and will also make the fabric a little tighter for cutting.

4) Let ‘em Rest

Old jeans fray more than most other fabrics when you cut them due to the fiber content and wear. For best results, once you wash your jeans, keep them folded and set aside until you’re ready to cut.

5) Cut Carefully

Because denim is thicker than many other fabrics and seams can be very difficult to cut through, I recommend using a rotary cutter. It will make it easier to cut through seams while minimizing hand strain and reducing fabric “crumbs.”

If you decide to cut with scissors, use a good pair of fabric shears and take frequent breaks to stretch your hands.

Unless otherwise instructed by the project, start by cutting the hem at the bottom of the leg first and then cut the seams at the side of the legs. See Tip #6 for cutting tips if your project uses pockets. Otherwise, continue by removing any damaged pieces such as frayed fabric or holes from the leg before cutting into squares or strips for your project.

6) Plan for Pockets

Many upcycled denim projects make use of pockets. If you are going to use back pockets, carefully trim around the pocket seams, leaving as much space around the seams as you can.

If you’re using front pockets, remember that the pocket inserts aren’t visible from the front of the jeans. You may want to cut the front pockets from the wrong side of the fabric to be sure you include as much extra room around the pocket as you need for your project.

If you don’t plan to use the pockets, you can trim close to the seams and get more useable fabric from the legs.

7) Don’t Overwork Your Fabric

Upcycled denim has more stretch than new fabrics. This is especially true if it includes spandex or other fibers blended in the fabric. Minimize handling the fabric because so it doesn’t stretch and become misshapen. Instead of ironing, finger press pieces as you sew. Lay cut pieces flat when not in use.

8) Prep Your Machine

Upcycled denim is thick and durable, which is great. However, sewing with denim (and especially sewing over seams) can put stress on your sewing machine. In general, work at a slower speed and be cautious when working near pocket seams to avoid damage to your needle and/or sewing machine.

Also, get to know your machine! My Baby Lock Jubilant has a leveling foot (the J presser foot on most Baby Lock machines) that helps you sew over thick seams. You can find out how to use it in this video tutorial by Melly Sews. Your machine may have something similar.

9) Change Your Needle

Mary Beth from Tailor Made Cosplay says, “When sewing with denim, make sure you have a needle size that accommodates the thickness of the fabric. You don’t necessarily need a needle marketed as a ‘jeans’ needle, but a 14 – 16 is optimal, especially a new needle with a nice, sharp, point.

10) Adjust Your Machine

Vicky from Vicky Myers Creations says “If your sewing machine is struggling to use a denim needle, try a long stitch with a walking foot and stitch slowly.” (Vicky has more tips for sewing with denim in this video.)

11) Be Flexible and Have Fun!

Upcycled denim isn’t as predictable as store-bought fabric. Everything from the size, wear, style, fabric content, and brand can influence how much useable fabric you can get from an old pair of jeans.

This tutorial includes instructions for two variations of the classic log cabin quilt block: the Cabin in the Corner and the Courthouse Steps blocks.

Don’t expect perfection. Upcycled denim isn’t as uniform as new fabric. It’s got lots of character, it’s affordable, it’s durable, and it can bring back great memories! It’s also a great material for making an eco-friendly project.
