Thrifted sweatpants before the DIY

Here are the sweatpants I got from the thrift store.

Cutting off the pant legs

1. Cut the pant legs to make shorts

To make the shorts, grab a magazine, place it on the leg part of the sweatpants and cut away. You can use any desired length; just make sure you cut straight. 

Folding the pant legs to cut the other side symmetrically

Fold the pants in half and use the cut side as a guideline to cut the other side. 

Rolling up the ends of the shorts

2. Roll the edges upwards

Next, roll the bottom edge upward to your desired length. You can sew the folds in place if you wish.

Cutting the side seams of the pant legs

3. Cut the side seams of the pant legs open

For the top portion of this lovely DIY two-piece set, simply take the excess fabric from the sweatpants and cut it open along the side seams. Do this for both pant legs.

4. Sew the pant leg fabric together

Lay both pieces on top of each other, making sure they are right sides touching. Then, sew along the edge of one side of the fabric.

So, now when you open it up, you have one long piece to work with. 

Cutting off the sweatpant cuffs

5. Cut off the cuffs

Cut along the perimeter of the fabric piece to make a rectangular shape. 

Hemming the raw edges

6. Hem

To clean up the raggedy sides of the rectangle, fold in all four sides and pin. Then, sew to secure. 

Trimming the excess fabric

7. Trim the excess

As you can see, there is a lot of excess fabric. So, go ahead and cut it off. 

Attaching eyelets to the back of the top

8. Attach the eyelets

Next, attach eyelets on either side of the short ends. Make sure they are adjacent to each other. If you don’t know how to attach eyelets, watch this tutorial on how to insert an eyelet in fabric.

Threading cord through the eyelets

9. Thread cord to make the corset back

You can either use a cord or string to feed through the eyelets in a criss-cross method.

    Cute, but I would have liked to see the back with the eyelets finished. Very creative!
