What You’ll Learn

✅ Encase raw edges for a polished finish
✅ Create durable seams perfect for high-stress areas
What You’ll Need
🧵 Fabric scraps for practice
✂️ Sharp scissors or rotary cutter
📏 Seam allowance: I’ll be using a ⅝ inch seam allowance
🧷 Matching or contrasting thread, depending on your style
Step 1: Stitch the Seam
🧵 Place your fabric pieces right sides together and sew a straight seam with a ⅝ inch seam allowance.
Step 2: Trim One Side of the Seam
✂️ Trim one side of the seam allowance down to ¼ inch. This step reduces bulk and makes it easier to encase the raw edge.
Step 3: Press and Fold the Seam
✨ Press the seam allowances to one side, folding the untrimmed seam allowance over the trimmed one.
💡 Tip: Pressing with steam helps keep the folds crisp and neat.
Step 4: Stitch to Secure
🧵 Stitch close to the folded edge, securing the seam and encasing the raw edges.
✅ Settings: Use a slightly longer stitch length, about 3.0mm, for a cleaner finish.
Bonus Tip
👍 Flat-felled seams are perfect for garments that undergo a lot of stress, like jeans and jackets!
