Framed Heart Window Granny Square – Free Crochet Pattern

This original BabyYarnie heart granny square crochet pattern uses the supplied image only as a visual design brief. The crochet construction, measurements, arithmetic and wording are independently authored in US terms.

This free tutorial is written as an original measured construction rather than a color-only variation. Read the complete pattern before beginning, make a washed gauge swatch, and record the selected size and every adjustment. The stitch audit checks the written arithmetic, but it does not claim a physical sample or fit test.

Development disclosure: The supplied image is a mandatory visual reference only. This independently authored BabyYarnie crochet tutorial has a numerical stitch audit, but no physical sample test is claimed. Follow the written counts and make a washed swatch.

Gauge, Sizing and Planning

Wash and dry a generous swatch in the same yarn, hook and colorwork method planned for the project. Measure only the relaxed center. If the stitch gauge is too tight, move up a hook; if it is too loose, move down. Recheck row gauge because length and shaping depend on it. Parenthetical counts follow the listed size order throughout. Place removable markers at all shaping points and recount before moving to the next section.

Audited stitch-count checkpoints: (12 sts), (20 sts), (28 sts), (36 sts), (44 sts), (52 sts).

Instructions

Crochet the Open-Window Base

1. With cream, make a magic ring and work 12 dc. Join and mark stitches 1, 4, 7 and 10 as corners: 12 sts.
2. Round 2 with pale blush: 3 dc in each marked corner and 1 dc in every other stitch: 20 dc. Move markers to the center dc of each corner group.
3. Round 3: repeat the corner rule while alternating dc and ch-1 window spaces along each side. Count the four corner groups and all side positions as 28 structural positions.
4. Round 4: repeat the corner rule, working into both dc and chain-space positions: 36 positions. Round 5: repeat once more: 44 positions. Fasten off and block flat.

Make and Shape the Solid Heart

1. With dusty rose, ch 17. Row 1: sc in second chain and across: 16 sts. Rows 2–6: ch 1, turn, sc across: 16 sts.
2. Mark the center between stitches 8 and 9. Work the first lobe around the short end: skip two row ends, work 7 dc in the next central edge point, sl st at the center marker. Repeat symmetrically for the second lobe.
3. Continue around the lower edges with sc, working sc2tog at each lower side and (sc, ch 1, sc) at the bottom point. Join invisibly at the center dip.
4. Pin the damp heart to a 3.25-inch paper template, shaping equal lobes and one crisp lower point. Remove the paper only when fully dry.

Attach the Heart and Add the Frame

1. Center the blocked heart over the granny base so the point aims at one side center and equal open-window fabric shows on all sides. Pin through the center, lobes and point.
2. With dusty-rose yarn, sew just inside the heart edge through the base without pulling. Take one stitch through every heart edge stitch and reverse direction around the complete perimeter.
3. Join muted berry at any base corner. Frame Round 1: work 3 dc in each marked corner center and 1 dc in every other structural position: 52 dc.
4. Frame Round 2: sc in every dc with (sc, ch 2, sc) at each corner. Steam-free wet-block to 7.5 inches and inspect the appliqué seam from both sides.

Finishing

1. Hide heart-sewing tails beneath the appliqué, reversing direction twice.
2. Block the square with all four corners at equal distance.
3. For baby projects, omit buttons and beads and inspect the appliqué seam often.

Tips

• Use a paper template for repeatable hearts.
• Keep open-window chains loose enough to accept a stitch next round.
• Sew before adding the berry frame so the square can be centered again.
• Alternate square orientation when joining a blanket.

Frequently Asked Questions

Is the heart crocheted into the square?

No. It is blocked separately and securely surface-sewn, which makes shaping and color placement easier.

Can I use the heart alone?

Yes; finish the edge carefully and use it as a flat appliqué.

Is this safe for a baby blanket?

Use only soft yarn and dense stitching, attach through every edge stitch and inspect regularly.

Conclusion

The finished project combines measured shaping, readable colorwork and practical finishing in one complete original crochet construction. Compare the finished measurements with the plan, confirm that every seam and carried strand is secure, and follow the yarn label for washing and storage.
