Choosing the Right Fabric
The fabric you choose will impact the liner’s functionality and appearance. Here are some popular options:
- Cotton: Breathable, easy to work with, and available in countless colors and patterns. Ideal for everyday use.
- Linen: Durable, lightweight, and has a beautiful texture. A more sophisticated look.
- Quilting Cotton: Offers a wide range of prints and is easy to sew. Good for adding a decorative touch.
- Waterproof PUL (Polyurethane Laminate): Excellent for protecting against spills and moisture. Perfect for gym bags, diaper bags, or travel totes.
- Ripstop Nylon: Lightweight and durable, often used for travel and outdoor applications.
Consider the bag’s intended use when selecting your fabric. For delicate items, a smoother fabric like cotton or satin is best. For heavier items or protection from spills, PUL or a heavier canvas is a good choice. Interfacing can add structure, particularly for larger bags or thinner fabrics.
Taking Accurate Measurements
Precise measurements are crucial for a well-fitting liner.
- Width: Measure the inside width of your bag at the widest point.
- Height: Measure the inside height of your bag from the bottom to the top edge.
- Depth: Measure the inside depth of your bag from side to side at the bottom.
- Add Seam Allowance: Add 1/2 inch (1.3 cm) to all measurements for seam allowances. This will ensure a comfortable fit.
For example, if your bag measures 12″ wide, 15″ high, and 6″ deep, your fabric cutting measurements will be 13″ wide, 16″ high, and 7″ deep.
Step-by-Step Liner Construction: Simple Slip-In Liner
This is the easiest type of liner to make, perfect for beginners.
Phase 1: Cutting the Fabric
- Cut two pieces of fabric (and interfacing, if using) according to your calculated measurements.
- If using interfacing, fuse it to the wrong side of one of the fabric pieces.
Phase 2: Sewing the Sides
- Place the fabric pieces right sides together.
- Pin or clip the sides and bottom edges together, leaving the top open.
- Sew along the pinned edges with a 1/2 inch seam allowance. Backstitch at the beginning and end of each seam to secure the stitches.
Phase 3: Finishing the Edges
- Trim the seam allowances to 1/4 inch.
- Press the seams open.
- Finish the raw edges with a zigzag stitch, serger, or bias tape to prevent fraying.
Phase 4: Turning and Pressing
- Turn the liner right side out.
- Gently push out the corners.
- Press the liner flat, ensuring a crisp finish.
Step-by-Step Liner Construction: Zippered Liner
A zippered liner offers extra security and keeps belongings contained.
Phase 1: Preparing the Zipper
- Cut a piece of fabric slightly longer than the bag opening’s width.
- Place the zipper right side down along one long edge of the fabric.
- Pin or clip in place.
- Sew the zipper to the fabric using a zipper foot.
Phase 2: Attaching the Liner Panels
- Cut two fabric pieces as described in the Slip-in Liner instructions.
- Place one fabric piece right side to the zipper. Pin or clip in place.
- Repeat with the second fabric piece on the opposite side of the zipper.
- Sew along the pinned edges.
Phase 3: Finishing and Turning
- Sew the side and bottom seams as described in the Slip-in Liner instructions.
- Trim seam allowances and finish raw edges.
- Turn the liner right side out through the zipper opening.
- Press the liner flat.
Adding Pockets (Optional)
Pockets add extra organization to your liner.
- Cut fabric for the pocket(s) to your desired size.
- Fold over the top edge of the pocket piece and press.
- Fold over again and stitch to create a finished edge.
- Pin or clip the pocket(s) to the inside of one of the liner panels before sewing the liner together.
- Stitch the pocket(s) securely to the liner panel.
Pro Tips
- Pre-wash your fabric: This prevents shrinkage after the liner is sewn.
- Use a walking foot: A walking foot helps feed multiple layers of fabric evenly, especially when working with thicker fabrics or interfacing.
- Corner clipping: Carefully clip the corners of the liner before turning it right side out. This reduces bulk and creates sharper corners. Be careful not to cut through the stitches!
- Topstitching: Topstitching along the top edge of the liner adds a professional finish and prevents the fabric from stretching.
- Coordinate fabrics: Choose fabrics that complement your bag’s exterior for a cohesive look.
When to Seek Professional Help
If you’re struggling with a complex pattern, working with difficult fabrics, or simply don’t have the time, consider asking a local seamstress for assistance. They can create a custom liner to your exact specifications.
FAQ
Q: What fabric is best for a waterproof liner?
A: Waterproof PUL (Polyurethane Laminate) is the best choice for a completely waterproof liner. It’s designed to repel liquids and is easy to clean.
Q: Can I use felt for a bag liner?
A: While you can use felt, it’s not ideal. Felt tends to pill and doesn’t hold its shape as well as woven fabrics.
Q: How do I measure a bag that isn’t a simple rectangle?
A: Take multiple measurements at different points and average them out. Focus on the widest and tallest points for the most accurate fit.
Q: My liner is too tight. What did I do wrong?
A: You likely didn’t add enough seam allowance to your measurements. Remember to add 1/2 inch to all dimensions.
Alternative Solutions
If sewing isn’t your thing, consider using pre-made fabric boxes or organizers that fit inside your bag. These are readily available online and in stores, but they may not offer the same custom fit as a sewn liner.
