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.
Customers praised the pattern as "very easy to follow" with "clear instructions" perfect for all skill levels. The zip romper is popular for kids' fleece sleepwear and layering. Some noted challenges using 4-way stretch fabric with zippers, recommending 2-way stretch instead. Overall highly recommended.

I made my Granddaughter who is 5 some fleece sleepsuits to keep her warm in the cold weather. Pattern was very easy to follow and instructions were very clear. Really pleased and Granddaughter is really happy with her new onesie.

My 6 and 9 year olds were wanting onesie's but not silly ones. I sewed my 6 year old's with a contrasting zipper, super cute. My 9 year old boy I made up in a mid weight 4 way stretch. The body was fine but it struggled with the difference in stretch between the fabric and the zipper, so next time just a two way stretch. Getting the collo

Loved it! Thanks for great pattern.

Love the Zip Romper, I like the zipper better than snaps or buttons and as always the instructions are so easy to follow they always make sure to write them as if you were a newbie and I feel that's awesome because not always have you done everything in sewing so you may be an expert in some things but in others you may very well be a newbie! And they are conscious of that! I love all the patterns I have purchased from here and there are way too many to count! I highly recommend this pattern and all the others! 💜💜💜

I love this one piece zip romper! Made with a stretch fleece and it’s the perfect layering piece for winter days or cozy days at home. Don’t be intimidated by the zipper, the step by step instructions are great!
