How to Print and Assemble a PDF Pattern Correctly

How to Print and Assemble a PDF Pattern Correctly

PDF sewing patterns are a great way to access beautiful designs instantly — but printing and assembling them can feel confusing the first time.

In this post, I’ll walk you through the exact steps I recommend, so you can confidently print, cut, and tape your pattern together — and start sewing without stress.

Step 1: Download the File & Open It in Adobe Reader
Always open the file using Adobe Acrobat Reader, not your browser.
Why? Because browsers sometimes scale or distort the file. Adobe Reader is free and ensures everything prints to scale.
Tip: You can download Adobe Reader here.

Step 2: Check the Paper Size & Print Settings
Most patterns come in A4 or US Letter size. Make sure you’re using the right format for your region.
When printing, these are the most important settings:

  • Scaling: Set to Actual size or 100%
  • Orientation: Auto or Portrait
  • Paper Size: A4 or Letter (match the file!)
  • Print pages: Start with just page 1 to test

Step 3: Print the Test Square First
Almost all PDF patterns include a test square (usually on the first page).
Print that single page and measure the square.
If it’s 5 cm x 5 cm (or 1" x 1") exactly, you’re good to go.
If it’s even a little off, don’t print the rest yet — check your settings again.

Step 4: Print All Pages
Once the test square is perfect, go ahead and print the full pattern.
If your pattern includes multiple sizes or layers, some designers allow you to print just your size by turning off other layers (in Adobe Reader, under the “layers” icon).

Step 5: Trim the Pages (If Needed)
Some patterns need trimming, others use overlapping margins.
If trimming: use a paper cutter or scissors to cut the right and bottom margins only.
If overlapping: check the markings and follow the layout diagram.

Step 6: Tape or Glue the Pattern Together
Align the pages using the notches, numbers or guides.
Start from the top left and work row by row.
Use clear tape, or a glue stick if you prefer.
It should feel like putting together a puzzle — just take your time.

Step 7: Cut Your Size
Once assembled, you can either:

  • Cut directly on the paper (if you're using one size)
  • Or trace your size onto pattern paper if you want to keep the original.

Bonus Tips:

  • Store your printed patterns in large envelopes or folders with labels.
  • Use a pattern weight or magnet to keep everything flat while cutting.
  • Some people even use a rotary cutter to trim pages — faster than scissors!

It might feel tricky the first time, but once you’ve done it once or twice, you’ll fly through it.

And if you’re using one of my patterns, I always include a test square and clear page numbers to make the process easier.

Happy sewing! ✂️
