When attaching non-fusible interfacing, start by cutting out the pattern pieces from both the fashion fabric and interfacing, matching them up raw edge to raw edge. Pin the interfacing to the wrong side of the fabric with just a few pins to avoid distortion.

Then stitch the two together using a slightly shorter seam allowance for the interfacing. Trim away any excess close to the stitching before repeating this process for any other matching fabric pieces.

Cutting Out Pattern Pieces

Once you’ve got your pattern pieces cut out, you’re ready to add structure with some sew-in interfacing – interfacing can improve a garment’s durability by up to 40%. Carefully cut out your fabric pieces according to the pattern guidelines first. Then use those cut pieces to trace and cut the interfacing to precisely match each fabric shape.

Take care to cut along the grainline and lay out interfacing pieces as you did the fabric. With pattern pieces and interfacing prepared, you’ve completed the first step towards a structured, reinforced garment.

Pinning Interfacing to Fabric, Matching Raw Edges

After carefully aligning, secure the fabric and interfacing together along their unfinished edges with pins, taking care not to distort either layer. Matching the raw edges provides structure and support. Use pins sparingly to prevent warping.

Proper alignment prevents problems later. Choose interfacings wisely for your project’s needs. Aligning raw edges prevents distortion when joining layers. Pins hold interfacing to fabric temporarily.

Stitching Interfacing With a Slightly Shorter Seam Allowance

You delicately fuse the interfacing 1/8 inch shy of the seam for a professional finish. Stitch the interfacing with a slightly shorter seam allowance, trimming the excess close to the stitching. This technique allows the interfacing to add structure without peeking out from the seam stitch.

With practice, you’ll master precise seam allowances when attaching interfacing for polished sewing projects. Expert tips like a shorter seam allowance ensure professional interfacing application and a flawless sewing finish.

Trimming Excess Interfacing Close to the Stitch

Next, carefully trim the excess interfacing close to the stitching line.

  • Use sharp scissors for precise trimming.
  • Avoid pulling or distorting the fabric.
  • Keep the trim line straight and even.
  • Leave 1/8 of interfacing beyond stitching.
  • Remove all loose threads and fuzz.

Following these simple tips when trimming excess interfacing will give your project a clean, professional finish. Proper trimming technique is key for smooth seams and a neatly reinforced fabric layer.

Repeating the Process for Matching Fabric Pieces

Once the excess interfacing is snipped away, it’s as if Cinderella is slipping into her glass slipper as the fabric pieces match up flawlessly. Next, pin and stitch the matched fabric pieces together to form a seam. Apply interfacing repeatedly to all matching fabric sections.

Proper preparation guarantees professional outcomes. With fabric correctly fused, you are set to sew.
