My daughter absolutely loves them
"My daughter absolutely loves them and I love making them. She likes the mid ones the most. They are so fast and easy to make🍓"
Unders
$5.00
With this super simple pattern, sewing undies has never been easier! It comes in low, mid or high rise and you can choose binding or bands. It's the perfect way to use up all of those fabric scraps!
We love sewing these into skirts and shorts as built-in undies too!
Pattern Type:
PDF - Letter, A0, Projector
Skill Level:
Beginner - anyone with a machine can do it! All you need is a regular sewing machine.
Fabric amount requirements:
All sizes : 1/2 yard / .5 meters
Materials: Jersey Knit is a great fabric for these unders! Cotton/lycra is generally the best blend but you can use any knit with decent stretch and recover. Rib knit works as well but we suggest sizing down if using rib knit.

A quick note before you dive in: Our patterns include multiple files so you can sew the way you like—at home on a printer, at a copyshop (A0), or with a projector.
Quick answers
- After checkout, you can download your pattern from the confirmation page, from the email we send, or anytime under Account → My Downloads using the same email you purchased with.
- Your files come in a .zip. It’s easiest to download on a computer, unzip, and you’ll see: Instructions, Letter/A4, A0, and a Projector file.
- Printing at home? Open the Letter/A4 PDF in Adobe Acrobat Reader and print at 100% (Actual Size), then check the test square.
- Prefer no paper? Use the Projector file. It includes a calibration layer so you can confirm scale before you cut.
- Need a big print? Send the A0 file to a local copyshop or an online printer.
- If you get stuck, email hello@lowlandkids.com and we'll be happy to help!
⸻
Downloads & accounts
How do I get my files?
Right after payment you’ll see a download button on the confirmation page. We also email you links in your order confirmation email. And you can log in to our website any time and find everything under View Downloads.
What pattern files are included?
Four PDFs: Instructions, Letter/A4 (home printing), A0 (copyshop), and Projector.
Can I download on my phone or tablet?
Yes! Check out our Printing and Projector tips page for specific guidance.
⸻
Projector sewing (quick start)
Do your patterns include projector files?
Yes—our current catalog includes projector-optimized files for nearly all patterns. You’ll see “Projector” listed in each download.
How do I check scale?
Open the Projector file and turn on the calibration layer. Confirm the 1” / 2.5 cm squares measure correctly. If you move your projector or cutting surface, re-check before you cut.
Any setup tips?
Keep the text/markers layer visible. If labels look faint, check your PDF viewer’s accessibility settings and disable “replace document colors.” You can also enable the black background layer for higher contrast.
⸻
Print-at-home (Letter/A4)
1. Open the Letter/A4 PDF in Adobe Acrobat Reader.
2. In the print dialog, choose Actual Size (100%) and auto portrait/landscape.
3. Print the page with the test square first; measure to confirm scale.
Troubleshooting:
- If the whole pattern prints on a single page, you likely opened the wrong file (use Letter/A4, not A0 or Projector).
- If lines look fuzzy or misaligned, try “Print as image,” make sure your printer driver is up to date, and restart your computer.
⸻
Copyshop / A0
Download the A0 file and send it to a copyshop or an online service. Many sewists print a single master copy and trace sizes as needed.
Note that we protect our patterns by locking the pdf files to prevent editing in tools like Adobe Illustrator. In rare circumstances copy shops might use software that invisibly requests edit access and will show errors when attempting to open our files.
⸻
Layers (print only the sizes you need)
All patterns include layers. Open the Layers panel in Acrobat Reader and hide sizes you don’t need. This keeps lines clear and makes grading between sizes easier.
⸻
Sizing & skill level
Each product page shows the skill level and links to the size chart. If measurements land between sizes, it’s common to use the width of one size and the length of another.
⸻
What machines do I need?
A regular sewing machine is all you need to start. A serger is optional but great for knit fabrics and tidy seams. A coverstitch is helpful for professional hems but not required.
⸻
Can I sell what I make?
Yes—items must be sewn by you personally. Mass production or outsourcing isn’t allowed. For manufacturing inquiries, email us.
⸻
Need help?
We’re happy to troubleshoot downloads, printing, or projector setup. Email hello@lowlandkids.com and include your order email and a screenshot of your issue if you can.

Unders
"Easy to do and great use of some smaller leftover knit pieces."
Made lots of unders!
"Whipped up several pair in no time at all -I feel it does require a serger and a cover stitch machine. Would love to see a static flap of some sort to make them meet my grandson’s approval. The mid rise unders are a standard size that most kids are used to. I have only tried the seamless version with bands. I do want to try the binding method."
Love it! ♥️
"Love it! ♥️"
So easy and quick
"Loooove this pattern. Took me a few tries to really understand the instructions with the insert, but I got it! I make the midrise with liner options for now."
Unders
"Good"
Unders: easy sew
"My granddaughter loves her Unders undies. Easy sew and a great scrap buster. I love the different low-med-high rise options."
Good but I have a few suggestions
"This is a nice pattern. It fits much better than the vintage kids briefs pattern I was using, and my daughter requested a wardrobe of these instead. We did alter the pattern a bit- we needed more fullness in the rear to fully cover and prevent wedgies. I also did overlap zig zag seams to mostly avoid seams that can be irritating. We used actual elastic in the waistband because the fabric band does not stay up with active kids. Lastly, the sizing- I wish there were larger sizes of this because my 5 year old is already wearing the 6/7, and my 7 year old is already at the largest size of this pattern. I would say the sizing runs small on this pattern. (My kids are athleticly built so I wouldn't expect them to have to go up in sizing, they aren't chubby or anything. ) I'm still glad I purchased this pattern, but would love to see a free add on for larger sizes for those of us who already purchased this pattern."
Undies
"Made several of these for my little girl in the high waist option. She loves them and says they are so comfy!!"
Obsessed!
"I love how easy these were to sew! I chose bands instead of binding. :) Mt daughter loves them"
