Before You Begin
Skill Level: Beginner
Technique: Foundation Paper Piecing
Time Required: About 20–30 minutes
Tools Needed: Printed foundation pattern, sewing machine, rotary cutter, quilting ruler, Add-a-Quarter® ruler (optional), postcard or folding tool, iron, fabric
Introduction
Foundation Paper Piecing (often called FPP) is a quilting technique that uses a printed paper foundation as a sewing guide. Instead of sewing pieces together first and hoping everything lines up, you'll sew directly on the printed lines, creating crisp points and accurate shapes that would be difficult to achieve with traditional piecing alone.
It may feel a little different the first time you try it, but once you understand the process, it's surprisingly straightforward—and incredibly accurate.
Before You Start
Take a moment to look over your foundation before sewing.
Notice that:
The printed side is the sewing side.
The numbered sections indicate the order you'll sew the pieces.
Fabric is placed on the back (unprinted) side of the paper.
You'll sew on the printed lines from the front of the foundation.
Understanding which side you're working on is one of the biggest hurdles for new FPP quilters, so don't worry if it feels backwards at first!
Step 1 – Position the First Fabric
Place the first fabric on the back of the foundation so it completely covers Section 1, extending at least ¼" beyond all surrounding sewing lines.
Since this first piece isn't stitched yet, many quilters use a fabric glue stick or a pin to hold it temporarily in place.
Remember, you are still sewing right sides together, so your first fabric should be RIGHT SIDE UP!
Step 2 – Add the Next Piece
Place the second fabric right sides together with the first fabric, aligning the edge that will be sewn.
Hold both fabrics in place and turn the foundation over so the printed side faces up.
Hint: When you are placing your fabric for piece 2, if the fabric covers the entire section when the paper is folded, when you press the fabric after sewing it should fit. Make sure you have fabric big enough to cover the seam allowances.
Step 3 – Sew on the Printed Line
Starting a few stitches before the line begins and ending a few stitches beyond the line, sew directly on the printed sewing line.
Many quilters reduce their stitch length slightly for Foundation Paper Piecing. Smaller stitches make removing the paper much easier later.
Step 4 – Fold and Trim
Fold the paper back along the stitched line.
Using an Add-a-Quarter ruler or a regular quilting ruler, trim the seam allowance to ¼".
This creates a consistent seam allowance before opening the fabric.
Step 5 – Press the Fabric Open
Open the newly added fabric and press it flat.
The new piece should completely cover its numbered section with at least a ¼" margin beyond the surrounding sewing lines.
Continue adding fabrics in numerical order until the section is complete.
Finishing the Unit
Once all pieces have been added, trim the completed section on the outside trimming line. If you don’t see an outer trimming line, use a ruler and cut 1/4” from the sew line.
Leave the paper attached until you're instructed to join sections or until your pattern tells you it's time to remove it.
My Tip
One of the easiest ways to avoid mistakes is to pause before every seam and ask yourself, "Will this fabric cover the entire next section when it's folded open?" I still do this after years of Foundation Paper Piecing, and it has saved me from ripping out plenty of seams.
Frequently Asked Questions
-
Always sew on the printed side of the foundation. The fabric stays on the back.
-
I recommend it. A shorter stitch length perforates the paper, making it much easier to remove after the block is complete.
-
Leave the paper attached until your pattern tells you to remove it. In most cases, the paper helps stabilize the block while joining sections.
-
No. It's a helpful tool that speeds up trimming, but a regular quilting ruler works perfectly well.
-
This usually means the fabric wasn't positioned far enough beyond the sewing line before stitching. Before every seam, fold the fabric open mentally (or physically) to make sure it will completely cover the next numbered section.
Just a hint, if the fabric covers the folded paper when laying face up, it SHOULD cover it when you press. If not, check your paper fold line to make sure it is exactly on the sewing line.
