Jolt Top Written Directions

The Jolt Top comes with two different versions- one with a fixed strap and one with a sliding strap. In these written directions we'll be going over how to make the stationary version. If you prefer to make a fixed strap, you can follow the video instructions from the tutorial below.


-Jolt Top PDF Pattern

-1/2 yard of swimwear fabric

-1/4" Swimwear elastic (recommended for the best fit)

-Seam ripper

-Loop turner

-Regular sewing machine (for straight stitch)

-Overlock machine OR zig-zag stitch on a regular sewing machine

Step 1

Assemble the pattern by taping together your pieces. In these instructions we'll be making the version with a sliding strap on the bottom, which allows for maximum adjustability. Make sure to use pieces 3 & 4 for this.

Step 2

Cut your pieces. You'll cut two of each bust piece, for a total of 4 pieces. Seam allowance is included in the pattern so there's no need to leave extra.

Step 3

You will also cut your straps according to the measurements provided in the pattern.

Step 4

Match the bust pieces with right sides together and sew along the marked areas. For the areas marked in green, you may attach elastic if you choose to do so. Note that you need to leave openings for the strap channels.

Also in this step, sew your straps by folding them in half lengthwise and attaching elastic.

Step 5

The areas marked in pink will be strap channels. Double check to make sure you've left either side of the strap channels open, large enough to fit a strap through. If you need to, get out your seam ripper and rip to make sure there's enough room.

Step 6

Now it's time to take each bust piece to the right side. You can do this through any of the strap openings.

Step 7

Once the bust pieces are right side out, it's time to sew the strap channels. Using a straight stitch, sew down each of the channels marked in pink dotted pink. You'll want to sew about 1/4" away from the edge for each channel.

Step 8

Finally, take each of your straps and thread them through the appropriate channels.

That completes the Jolt Top!
