🧵 Mattress Stitch
Best for: Seaming knit garments (especially stockinette), vertical seams, or anything where you want the seam to disappear.
Use it when:
- You’re joining two vertical edges, like the sides of a sweater body or the sleeves.
- You want an invisible seam from the right side.
- You need the seam to stretch with the fabric, especially in fitted garments.
Why it’s great:
- Creates a clean, professional finish.
- Seam is nearly invisible on the right side.
- Preserves the continuity of the stitch pattern.
Bonus tip: Works beautifully when joining crochet pieces made with stitches like slip stitch or single crochet, but it’s more commonly used for knitting.
🪡 Whip Stitch
Best for: Quick, simple seaming; crochet garments; or joining motifs like granny squares.
Use it when:
- You’re sewing crochet pieces together, especially if you don’t mind a visible seam or want a decorative ridge.
- You’re joining edges with texture or irregular shapes.
- You want a seam that’s fast and forgiving.
Why it’s great:
- Super easy to do—even beginner-friendly.
- Good for bulkier yarns or thick textures.
- Great when you want a little structure or edge definition.
Caution: Whip stitch can show on the right side, and may pull tight or pucker if you're not careful.
🧷 Back Stitch
Best for: High-stress areas, or when you need a very strong seam—especially for seams that will be under strain (like shoulder seams or underarms).
Use it when:
- You need a super strong and secure seam that won’t budge.
- You’re sewing in curves or set-in sleeves, where control matters.
- The seam will be mostly hidden or you're fine with it being visible.
Why it’s great:
- It’s like machine sewing—strong, stable, and dependable.
- Excellent for structured garments or places with tension.
Caution: It’s less stretchy than other seams and can add bulk if done too tightly.
