How To Sew Your Own Rash Guard Shirt
So whether you live by the “modest is hottest” approach or you are actually surfing some waves, this Women’s Rash Guard Tutorial will show you just how EASY it is to make yourself one!
If you have ever sewn a simple shirt for a child or yourself, you can do this! If you haven’t, don’t be afraid to try! All you need is a some swimsuit fabric or a spandex lycra mix fabric. I found this print at Hancocks on sale! It matched my Land’s End flouncy swim skirt perfectly! I used about 1.5 yards and spent $16 on the fabric! Pretty awesome when compared to most brands!
- 1 – 2 yards of swim suit fabric or spandex lycra mix fabric, depending on your size
- A tighter fitting shirt you can draft from -OR- a basic shirt pattern to adapt
- A twin needle, 75 or 80, depending on the weight of your fabric
- Sewing machine & supplies, serger (optional)
Since most of us have a basic shirt pattern we love, I’m not going to walk through the actually drafting process with you today. I altered my Megan Nielson Briar pattern pieces, since they are simple basic blocks, to create my rash guard. You need 2 sleeves, a front, a back, and a neckline band.
The rule of thumb, is to size DOWN one size.
Even after I sized down, I tried my shirt on and took more off the waist. I didn’t want anything floating up and around in the water, so you want a snug fit hugging your body. Everything gets loose in water, so make sure it fits you well!
Cut out your pieces like so!
I cut my neckline band 2 inches x 10 inches, but you may need to adjust for your size.
Ready to sew?!
Adjust your machine to have a longer stitch length on a regular sewing machine, around 4.5 in length OR use a zig zag stitch OR triple stretch stitch, if your machine has that option! Anything to allow some give to your knit. If using a serger, set according to your manual for a 4 thread overlock for stretch fabrics. Test your fabric to ensure you have no waves and adjust your differential feed to make it smooth, if necessary!
Pin your shoulder seams and sew/serge right sides together.
Using a shirt with your desired neckline, cut out your neck hole. It’s good to try your shirt on over your head, make sure it works, take it off and adjust where necessary, making a deeper front line or curve.
Next, sew/serge the short ends of your neckline band right sides together.
Fold your neckline band in half lengthwise.
Pin right sides together your neckline band to your neck opening. You will have 3 layers together here. Mark the center points with pins and then work it around to make sure all fabric is flat and there are no puckers. You may have to stretch the neck band a bit to make it work. As long as it fits over your head, you are good-to-go! Test it, if needed!
Sew/serge your neck band to your neck right sides together.
Next, pin your sleeves to the shoulders right sides together at the center point and work your way out towards each arm pit where it meets the side.
Sew/Serge your sleeve to the arm hole.
Now, we are ready to do a little twin needles sewing! I recommend this for hemming any knits, because it looks so professional on the outside and still allows the give you need for stretching over your head, waist, and wrists!
I remember being so intimidated by this technique when I first started sewing, and then when I finally sat down and realized it was simply just changing my needle, hitting the double needle button on my machine, and using an extra bobbin? I was SOLD!
All you do is wind an extra bobbin with the same top color you need. Thread your machine normally, allowing this thread to go into the left needle. Then, thread your machine a second time, but this time don’t go behind the needle bar, but just let it hang free and thread through the right eye of the needle. I know this seams funny, but it works great! The only other things you need to remember is to set your stitch to a center stitch and select the double needle button on your machine! You are ready to go! Start hemming those sleeves and waist hems! Since this swim fabric doesn’t fray, just fold 1/2” towards the wrong side and sew it down!
See how it creates a zig zag on the back, but looks so neat on the front? It makes my heart happy!
This may be a preference, so if you want a neck collar that stands up, you can leave it! To make it look like bias binding, just pin it over and use that double needle to sew it down, making sure to catch the back layer, so it lays flat.
And that’s it! You just made a Rash Guard swim shirt!
Now, go have some fun in the sun!
Next up for me, will HAVE to be sewing rash guards for the kids!
Making one for myself first was fun, and seeing how easy it is, I will definitely be making some for my son and nieces and nephews! Thanks for joining me today!
