GoldenLucyCrafts Heart Keychain
A slim, neat heart that’s perfect for everyday use—this pattern shapes the top “bumps” first and tapers to a tidy point, then adds a jump ring for a clean bag charm look. It’s a quick make in worsted cotton; two panels are crocheted and seamed with a tiny stuffing so it stays puffy but not bulky. Expect ~12–20 g of yarn for a 2.5–3″ heart. Tip: block lightly before attaching hardware so the edges lie flat and the curve reads crisp. Add a charm or tassel for personalization, then clip to a swivel lobster clasp. Tutorial
Supplies: Worsted cotton (4) · 4.0–4.5 mm hook · Keyring/jump ring + lobster clasp · Fiberfill · Yarn needle
Why it’s great: Clean, giftable shape with lots of finish photos.
Crochet Heart Keychain Pattern
No magic ring needed! This beginner pattern builds the heart in simple rows of chains and single crochets, then stuffs and seams for a tidy puff. Great for quick favors or school swaps—each heart is about 2–2.5″ across with ~15 g of yarn. Tip: when stuffing, add tiny pinches at a time to keep the outline smooth; overstuffing can distort the point. Finish with a short chain loop or a jump ring before closing the seam so hardware sits securely. Tutorial

FAQs
What yarns work best for heart puff keychains?
Worsted cotton or acrylic holds shape and shows stitches cleanly. Chenille (super bulky) makes ultra-plush hearts—use a smaller hook to avoid gaps.
Machine wash or hand wash? Drying tips?
Hand wash in cool water, squeeze in a towel, then air-dry flat. If using cotton/acrylic, a gentle machine wash in a mesh bag is usually fine; avoid dryers for chenille.
How do I scale patterns up or down?
Change yarn weight and hook size (keep fabric firm). Heavier yarn + larger hook = bigger heart; lighter yarn + smaller hook = tiny charm.
Which fibers are safest for kitchen/bath or heat?
Cotton tolerates moisture and mild heat better than acrylic. Avoid placing any fiber near high heat sources; these are decor items, not trivets.
Best joins/edgings for durability?
For two-panel hearts, single crochet around both panels and stuff as you go. For in-the-round hearts, use an invisible decrease and secure hardware through multiple stitches.
Typical time and yardage?
Small hearts: 20–40 minutes, ~10–20 g of yarn. Chenille versions may take ~25 g. Add 5 minutes to attach hardware and weave ends.
How can I photograph my projects well?
Use daylight near a window, a plain background, and shoot overhead or at 45°. Get close so stitches are visible, and include the keyring for context.
Fixing curling, stretching, or wavy edges?
Block lightly with steam (cotton) or a spritz (acrylic). If fabric stretches, go down a hook size. For wavy edges, reduce stuffing and check stitch counts along the curve.
