How to Repair Upholstery Cushions and Covers

Ever wonder how pros sew buttons onto pillows, or how they get their cushions so perfectly straight and smooth? Unwrap the mystery of upholstery, and stitch together some skills to sew small projects and make repairs. I spent a day with Nate Van Hofwegen at his shop talking about his upholstery magic and what tricks he could teach us.

Nate Van Hofwegen has been an upholsterer for 20 years. His favorite projects are vintage van and motorcycle seats.

Use The Right Needles For The Material

Family Handyman

• Choosing the correct sewing needle for your material eliminates frustration and breakage.
• Van Hofwegen uses 140/22 needles for most of his vinyl projects. Leather and denim require thicker, stronger needles.

Make Your Pleats Neat

Family Handyman

• Making rounded corners and edges look consistent is not easy. Here are the steps Van Hofwegen takes to achieve the same look around the entire seat cushion.
• First, he gathers the material tightly around the corner and spaces the staples evenly.
• He then trims the excess material, snipping the crowns off the pleats.
• Finally, stapling about 1/2-in. from the edge, he fastens the loose tails so they lie flat.

Replace, Don’t Repair

Family Handyman

• We’ve all seen the upholstery repair kits that claim to “work like magic.” The problem is, they don’t.
• Often it’s easier to just replace your item. Sometimes you can’t beat new.

Choose the Right Fabric

Family Handyman

• Use the right material for your project — outdoor cushions need fabric designed to withstand the elements.
• There are even special types of vinyl that make repairing upholstery easier.

Cutting Foam

Family Handyman

• Van Hofwegen has a saw designed to cut foam. An everyday alternative to this pro tool is an electric bread knife.
• A bread knife’s serrated edges easily cut through thick foam. The knife is also lightweight and easy to control.

Stiffen Edges With Batting

Family Handyman

• Polyester batting stiffens a cushion and eliminates wrinkles, making a cushion cover taut and smooth.
• Glue the batting to foam with a spray such as 3M Headliner & Fabric Adhesive ($19).

Make A Pattern

Family Handyman

• When you’re making more than one of anything, a pattern is essential.
• Van Hofwegen suggests making patterns that account for the seam allowance, so you don’t have to remember to offset the line every time you trace the pattern.
• Van Hofwegen uses chalk, not markers, for marking his lines. Chalk isn’t permanent, and markers tend to bleed.

Lock Your Stitch

Family Handyman

• Backstitching locks a stitch in place, ensuring it won’t unravel.
• Start by going in reverse about an inch, and then go forward over that bit of stitching. This locks in the thread at the beginning of the seam.
• Do the same at the end of the seam.

Use A Special Foot For Zippers

Family Handyman

• Zippers and piping often require stitching closer to the edge than a regular foot will allow.
• For these operations, Van Hofwegen uses a special foot on his sewing machine.

Replace A Missing Button

• The buttons on a tufted cushion often come loose, get damaged or disappear. Van Hofwegen showed me how easy it is to replace them.
• With a long needle called a regulator and a simple knot, you can replace a button on any cushion.
