Pattern Instructions
Step 1: Prepare Granny Squares
Make 41 granny squares, each measuring 8 cm. If you are unfamiliar with granny squares, reference the earlier tutorial mentioned in the video. Ensure consistent tension and size.
Step 2: Assembling Front and Back Panels
- Use 2 squares for the front and 2 squares for the back.
- Place the squares with the right sides facing each other. The pattern’s heart shape must point upward.
- Locate the 2 chains in each corner of the square when joining. Work only in the outside loops:
- Insert your hook into the first chain from the front square and then into the corresponding chain of the back square.

- Perform a slip stitch to join. Repeat for the entire edge.
- Insert your hook into the first chain from the front square and then into the corresponding chain of the back square.
- Continue adding squares row by row following the required dimensions.

Step 3: Sleeves
- Three granny squares are used for each sleeve.
- Connect them similarly using the slip stitch method.
- Add two rounds of single crochets around the sleeve edges for a neat finish.

Step 4: Joining Sleeves
- Lay the completed front and back pieces flat.
- Position the sleeves on top, aligning the middle of the sleeve with the shoulder seam.
- Use the slip stitch technique to attach the sleeves.
- Ensure all hearts face the correct upward direction before fastening the yarn.

Step 5: Joining Side Seams
- Fold the panels and sleeves to shape the shirt.
- Begin slip stitching under the sleeve and down the sides of the shirt.
Step 6: Adding a Collar
- Count and mark 7 stitches on both sides of the neckline.
- Attach your yarn and chain 3 to begin the row, representing the first double crochet.
- Work double crochets around the neckline:
- In the first row, make an increase in the corner stitches (i.e., 2 double crochets in the same stitch).
- Continue for four rounds, increasing in each corner.
- Stop increasing in the 5th round for a smoother edge.
- The color rounds should total 6 cm when finished.
- Fasten off and weave in ends.
Step 7: Buttonholes
- Work a row of single crochets along the button panel.
- In the second row, create buttonholes:
- Chain 2 and skip a stitch where you want your buttonhole. Continue single crochets in other stitches.
- Ensure buttonholes align with buttons.
Step 8: Finishing Touches
- Sew buttons onto the opposite panel using a tapestry needle and yarn.
- Add any decorative touches or lining if needed.
- Weave in all loose ends to give the shirt a polished finish.

Tips for Customization
- Color Combinations: Experiment with different colors to suit personal preferences.
- Sizing Adjustments: Add or subtract granny squares to change the width or length of the shirt.
- Decorative Edging: Add a picot or scalloped edging for an elegant touch.
- Seasonal Theming: Use Christmas colored yarns or pastel shades for spring themed clothing.
