Hi Bestie,
Better projects start with the right support.
From crisp collars to cozy quilts, the layer you can't see is what makes the piece feel right. Pellon makes a whole family of those layers, and today we're sorting out which one does what.
1. Choose your project partner
Interfacing adds structure. Use it where your pattern needs extra support, such as collars, cuffs, pockets and facings.
Fusible fleece adds softness. A useful layer for select craft, home decor and sewing projects, especially bags.
Batting adds loft. It's the middle layer in a quilt sandwich. Choose the fiber and loft to suit your project.
2. Match the exact product
Pellon is a family of products, not one set of instructions. Check the style number, fabric compatibility and your pattern before you cut. Fusible and sew-in products are used differently, and a featherweight interfacing behaves nothing like a foam stabilizer.
A good example is SF101 Shape-Flex: a woven cotton fusible interfacing for crisp support and added stability. Because it's woven, it moves with quilting cotton instead of fighting it. Compare that to 988 Sew-In Fleece, which gives the same softness as fusible fleece with no adhesive for heat-sensitive fabrics.
3. Make a test piece first
Try the complete process on a scrap of your project fabric. Check the feel, appearance and bond before working on the real pieces.
Follow the product's preparation directions. Do not assume every interfacing should be washed or treated the same way.
4. Fuse with confidence
For fusible products, put the adhesive against the fabric's wrong side.
Follow the exact product directions for heat, steam, pressure, press cloth and pressing time.
Lift and place the iron rather than sliding it. Let the piece cool before checking the bond.
As an example, for 987F Fusible Fleece Pellon directs firm pressing for about 10 seconds, slightly overlapping each area. Let it cool, then check the bond. Product settings vary, so keep the instructions with your cut pieces.
Why "lift and place" matters
Fusible adhesive is a heat-activated glue in a dot or web pattern. It needs heat, pressure and a few seconds of stillness to melt into the fabric fibers. Sliding the iron drags the interfacing before the glue has set, which stretches the piece and leaves thin spots where the bond fails. Cooling flat is the second half of the same rule: the glue hardens as it cools, so moving the piece warm is like moving a cake before it sets.
5. Building a quilt?
Layer backing, batting and quilt top. Smooth and baste using your preferred method, then quilt within the batting's stated maximum stitch spacing. If you're still deciding how to baste, we settled the argument in Spray Basting vs. Pin Basting.
Check the label for shrinkage, care and whether the batting is fusible. Ordinary batting does not fuse with an iron.
6. Troubleshoot before you continue
Edges lifting? Let the piece cool, then recheck the product's heat, moisture, time and pressure requirements.
Too stiff? Test a lighter support that suits your pattern.
Heat-sensitive fabric? Check compatibility and consider a suitable sew-in interfacing. This is the same question we tackle in Which Stabilizer Should You Use?

What will you create next?
A polished collar. A structured pocket. A softly padded project. A cozy quilt. Plan your projects. Choose what you need.
Happy Quilting!

Frequently Asked Questions
What is the difference between interfacing, fusible fleece and batting?
Interfacing adds structure and crispness to collars, cuffs, pockets and facings. Fusible fleece adds a soft, padded layer with a bit of body for bags, crafts and home decor. Batting adds loft and is the middle layer of a quilt sandwich. They are not interchangeable; your pattern will usually name which one it wants. Browse all three in our Pellon collection.
Which side of fusible interfacing goes down?
The adhesive side goes against the wrong side of your fabric. Fusible products have a slightly bumpy or shiny side; that is the glue. If you fuse it face-up you will glue your iron instead of your fabric, so always use a press cloth and test on a scrap first. See the Pellon SF101 Shape-Flex guide for a step-by-step.
Why is my fusible interfacing lifting at the edges?
Edges usually lift when the piece was moved before it cooled, or the heat, time, moisture or pressure did not match the product directions. Let the piece cool completely flat, then re-press with a press cloth, lifting and placing the iron rather than sliding it.
Should I prewash interfacing?
Only if the product directions say so. Some woven interfacings like SF101 benefit from a pre-shrink soak; many non-wovens and fusible fleeces should not be washed before fusing. Do not assume every interfacing should be treated the same way; read the instructions that came with your cut.
Can I use regular batting in a bag instead of fusible fleece?
You can, but you will get a softer, floppier bag because batting has no adhesive and less body. Fusible fleece such as Pellon 987F stays put while you sew and gives a smoother finish. For a bag that stands on its own, a foam stabilizer like Pellon Flex-Foam is the better match.
