Summer is coming, and it’s time to think about swimsuits! I love sewing swimsuits for both boys and girls. I’ve already shared tips for sewing stretchy swimsuit fabric, but today I’m sharing how to make a boy’s swim trunks using two Simplicity patterns and the Cricut Maker*.

This was the first in-depth sewing project I used with the Cricut Maker*. As I was preparing my fabric to cut out, I wondered if the Maker would actually make my project faster. It was taking me awhile to cut the fabric just to fit on the mat.
Once I started watching the Maker cut out the pieces, I loved that it cut my fabric pieces, it marked my fabric, AND the notches were cut more accurately than any other project I’ve ever cut out. I loved not cutting out a pattern and not pinning it to fabric. And I really love that the hem was marked.
My favorite part was that I placed one piece of fabric on the mat wrong, so that the piece was cut incorrectly. Instead of placing the pattern piece somewhere else and pinning it again, I just had the Cricut Maker* cut that mat and pattern piece again. It was amazing and so fast to fix my mistake!
I used two Simplicity sewing patterns on Cricut Design Space to create this boy’s swim trunks. I used the Boy’s Boxer Shorts and baby Vintage bloomers. This is a fun and easy Cricut Maker sewing project!
The changes I made to the shorts were to use swim fabric instead of cotton. I also omitted the fly opening on the shorts.
The changes I made to the bloomers were to use stretchy swimsuit lining. I omitted the elastic at the legs since it fits like stretchy underwear on my boy. I also shortened the height of the bloomers so that they would fit inside the swim trunks.
I have had a boy for over six years which means I’ve been looking for boardshort fabric for over six years. There are not a lot of options! Sometimes I upcycle swimsuits to make the best swim trunks!
The two places I have found that have boardshort fabric is The Fabric Fairy and Raspberry Creek Fabrics. Both have their own styles, but they are both good quality. It mostly depends on the pattern and color you are looking for!
- Boardshort fabric
- Swimsuit lining
- Cricut Maker*
- Cricut washable fabric pen*
- Simplicity Pattern Boy’s Boxer Shorts – I used boardshort fabric and omitted the fly opening
- Simplicity Pattern Vintage Bloomers – I used swim lining fabric and omitted the elastic on the leg openings
- Sewing tools
- 3/4″ elastic
Before you get started and gather all your supplies check sizing and measurements on the pattern to make sure it will fit your child. The boxer shorts pattern provided a hips measurement, a side length measurement, and a leg circumference measurement. I measure my son and it was a great fit for him.
How to Make a Boy’s Swim trunks
- After measuring to make sure the pattern will fit, prepare the pieces of fabric by cutting them to the size recommended in the instructions.
- Set up your Cricut Maker* with your phone or computer. Place the first piece of fabric face down on the 12×24 fabric cutting mat. It’s really important that the fabric is face down so that the fabric pen writes on the wrong side of the fabric!
- Use the Cricut Maker* to cut out all the pieces. You should have two waistband pieces, two fronts, two backs, and two lining pieces.
- With right sides together and a straight stitch sew the inseams of the front and back pieces together. Finish the edges.
- With right sides together and a straight stitch sew the crotch seam. Instead of following the pattern to have a fly opening, I created a faux fly by following the outside of the fabric. Finish the edges.
- Use the markings to see where the center comes together to create the faux fly.
- Baste the fold at the top.
- With right sides together and a straight stitch sew the side seams of the trunks. Finish the edges.
- Finish the edge of the leg openings. Use the hem marking to fold the hem up and sew it.
- With right sides together and a zigzag stitch sew the two front seams of the swim trunks lining.
- With right sides together and a zigzag stitch sew the crotch seam together.
- Fold the leg openings up 3/8″ and sew around with a zigzag. This is the leg hem with no elastic added.
- I found that the swimsuit lining was just a tad tall, so I cut 1″ off the top of the swimsuit lining at the waist.
- Place the swimsuit lining inside the trunks with wrong side of the lining facing the wrong side of the trunks. Match up the center front and center back and pin all the way around.
- Sew the side seams of the waistband.
- Fold the waistband in half lengthwise with wrong sides together. Match up the notches and center front and center back. You will have four layers together: two layers of waistband, the lining, and the trunks.
- Sew the waistband on the trunks with a straight stitch. Leave a 3 inch gap to insert elastic.
- Cut the elastic the right length by measuring it on your child. Use a safety pin to insert the elastic into the waistband like a casing.
- Sew the elastic ends together and then sew the gap closed.
- Carefully press your seams with a cool iron.
Enjoy your amazing handiwork! You can make a boy’s swim trunks!
It’s perfect for running, playing, jumping, and swimming all summer long!
