DIY biker shorts pattern using leggings

1. Make the biker shorts pattern

Use a fabric that has a lot of stretch to it, almost like a legging material. Once you've decided on a good stretchy fabric, take your best pair of leggings and use it as your base to make biker shorts. 

You are going to be tracing out the front and back crotch so that you have one main pattern, as shown. 

Drawing the biker shorts pattern

You'll need a ½-inch seam allowance for the leg area and a 2-inch seam allowance for the waistline. 

Tip: Remember to cut out two of the same pieces, so fold your fabric accordingly.

2. Sew the biker shorts

Put the two pieces on top of each other and sew the side crotch seams, as shown. 

Matching the inner leg seams, ready to sew

Open up the pattern, match the inner leg seams, and sew. 

Sewing the elastic waistband for the biker shorts

3. Add the elastic

Cut a piece of elastic that sits comfortably around your waist, and sew the ends together.

I also like to open up the seam and sew it down with a zigzag stitch. 

Attaching the waistband to the biker shorts

My DIY biker shorts were a little too short at the waist area, so I sewed the elastic right on top of the waist. Before doing this, stabilize the fabric with a zigzag stitch. 

Stretching the elastic while sewing

Then, sew on the elastic by stretching it as you sew. 

Hemming the short legs with a double-fold hem

4. Hem the legs

Hem the bottom of the legs by folding them under twice and topstitching the fold all around.

    I think that when i make me some of these I will add some side pockets on them to hold my phone / money/ or keys ...I have a few pairs of biker shorts that have a side pocket but they only have one and i want one on each side .....thanks for sharing your idea on making these ...I might just buy me some cheap leggings and cut them down for the shorts and then use the material I cut off to make my pockets....yep sounds like a plan to me....
