Step-by-Step Detailed Crochet Instructions

Foundation: Connecting the Heart Motif to Start the Square

1. Insert the Hook in the Chain Spaces:
   • Identify the four chain 1 spaces from the heart motif.
   • Working on each corner will build the granny square.
2. Steps for Creating Corners:
   • Insert the hook into the first chain 1 space of the heart motif (bend the heart slightly if needed for visibility).
   • Work sl st in the chain space to attach the yarn.
   • ch 1, then sc in the same chain 1 space.
   • ch 3, then sc again in the same chain 1 space — this creates the first corner.
   • ch 6 to move to the next chain 1 space.

1. Repeat for Remaining Corners:
   • For each chain 1 space:
     • Skip three treble crochets from the heart motif.
     • Insert the hook between the third and fourth treble crochet (from the back).
     • Sc, ch 3, then sc again in the same space.
     • Ch 6 to move to the next corner.
2. Finish the Foundation Round:
   • After completing all four corners, ch 6 and join to the first single crochet with a sl st.
   • Ch 1, cut off yarn, and pull through.

Round 1: Starting the Granny Square

1. Attach Yarn:
   • Use contrast color yarn (e.g., green).
   • Make a slip knot and insert the hook into any ch-3 corner space.
2. Form the First Corner:
   • Sl st into the corner space to attach yarn.
   • Ch 3 (counts as first dc), then work 2 more dc in the same space.
   • Ch 2, and work 3 more dc into the same space. This forms the first corner.
3. Transition to Chain Spaces:
   • Ch 1, then insert the hook into a ch-6 space.
   • Work 3 dc into the chain 6 space.
   • Ch 1, move to the next corner.
4. Work Remaining Corners:
   • In the next ch-3 corner space:
     • Work 3 dc, ch 2, then 3 dc.
   • Transition again with ch 1 into the next chain 6 space and repeat.
5. Complete the Round:
   • After working all sides and corners, join to the top of the first ch-3 with a sl st.
   • Slip stitch into the next 2 stitches and finally into the corner ch-2 space to prepare for the next round.

Round 2: Continuing the Granny Pattern

1. Start the Round at a Corner Space:
   • Ch 3 (counts as 1 dc) and work 2 more dc into the corner space.
   • Ch 2, then work 3 more dc into the same corner space.
2. Work Along the Sides:
   • Ch 1, then work 3 dc into the chain 1 space of the side.
   • Repeat this pattern until the next corner.
3. Work the Corners:
   • In each corner space, continue: 3 dc, ch 2, 3 dc.
4. Repeat for All Sides:
   • Continue working clusters of 3 dc into each chain 1 space along the square.

Additional Rounds:

• Work as many additional rounds as desired by following the same granny square pattern:
  • In side spaces: 3 dc, ch 1.
  • In corners: 3 dc, ch 2, 3 dc.

Final Assembly

1. Final Round:
   • On the last round, complete with sl st to join to the top of the first ch-3.
   • Ch 1, cut the yarn, and pull through to finish.
2. Weave in Ends:
   • Use a tapestry needle to weave in any loose ends.
3. Blocking for Sharp Edges:
   • Lay the square flat on foam blocking mats.
   • Stretch and pin the corners using clips.
   • Spray lightly with water.
   • Let it dry completely for a polished look.
