Project Overview

This project is constructed from multiple individual granny squares, each beginning with a butterfly appliqué crocheted separately and sewn onto the center. Each granny square is worked in rounds with color changes to create a layered, bordered effect. The squares are then joined together using a visible join method, such as whip stitch or single crochet seam, to assemble the blanket and optional pillow covers. A simple yet elegant border completes the blanket, reinforcing the motif’s unified look.

Skill Level

Advanced Beginner to Intermediate. The project involves basic granny square construction, color changes, working in rounds, and making small butterfly appliqués, making it accessible to those comfortable with basic crochet stitches and techniques. Some sewing of appliqués is required.

Materials

Yarn: Approximate DK weight (#3 light) cotton or cotton-acrylic blend yarn. Suggested colors: Cream (A), Sage Green (B), Lilac (C), Lavender (D), Dark Plum (E for butterfly body and antennae).
Yarn Amounts:
- Cream (A): ~1400g / 2550 yds for blanket, ~150g / 270 yds for pillow cover.
- Sage Green (B): ~800g / 1460 yds.
- Lilac (C): ~400g / 730 yds.
- Lavender (D): ~150g / 275 yds.
- Dark Plum (E): Scrap amounts.
Crochet Hook: 4 mm (G-6) or size to obtain gauge.
Tapestry Needle for sewing and weaving ends.
Scissors
Stitch Markers for rounds and color changes.
Blocking Supplies (optional): pins and mat.

Finished Size

The blanket shown is approximately 135 x 180 cm (53 x 71 in), fitting a queen-size bed with generous coverage. Each granny square measures about 13 x 13 cm (5 x 5 in) after blocking. The pattern is highly adjustable—simply add or subtract squares for larger or smaller blankets, or modify the border width to fit specific sizes.

Gauge

Gauge is approximately 16 dc and 8 rounds = 10 cm (4 in) square, after blocking, using DK weight yarn and a 4 mm (G-6) hook. Exact gauge is not critical, but minor gauge changes will affect the finished size and yarn requirements. Make one square and block it for a gauge swatch before proceeding.

Stitches and Abbreviations

ch – chain
sl st – slip stitch
sc – single crochet
hdc – half double crochet
dc – double crochet
tr – treble crochet
MR – magic ring
inc – increase (2 sts in same st)
st(s) – stitch(es)
RS – right side

Pattern Notes

Turning chains DO NOT count as stitches in this pattern.
All rounds are worked with the RS facing, joining each round with a sl st to the first st (unless noted).
Fasten off after each color change and weave in ends neatly or secure with invisible joins if you prefer seamless transitions.
Sew butterfly appliqué securely at the center before joining squares for a neat finish.
Use stitch markers to mark the beginning of rounds, especially in the butterfly wings and the initial rounds of the square.
Your tension may affect the butterfly’s size; gently block finished items for uniformity.

Crochet Pattern Instructions

Butterfly Appliqué (Make one per square)

With Lilac (C) or Lavender (D), create a MR.
First Wing: Ch 3 (counts as dc), 2 dc, 3 tr, 2 dc, ch 3, sl st into ring. Tighten ring.
Second Wing: Ch 3, 2 dc, 3 tr, 2 dc, ch 3, sl st into ring. Fasten off, leaving a tail.
With Dark Plum (E), thread the tapestry needle and pass the yarn vertically through the center as a ‘body’, wrapping around a couple of times for dimension. Use remaining yarn to embroider short upward ‘V’ shapes for antennae.
Set aside for sewing to granny square.

Granny Square Base

With Cream (A), ch 4, sl st to form a ring, or use a MR.
Round 1: Ch 3 (counts as dc), 2 dc into ring, ch 2. (3 dc into ring, ch 2) three times. Join with sl st to top of beg ch-3. (4 groups of 3 dc, 4 ch-2 corners)
Round 2: Ch 3, 2 dc in same sp, ch 1, [3 dc, ch 2, 3 dc] in next corner, ch 1. Repeat around, ending with ch 1, sl st to join. (8 groups of 3 dc, 4 ch-2 corners)
Round 3 (switch to Lilac (C)): Join new color in any ch-2 corner, ch 3, 2 dc, ch 2, 3 dc in corner, ch 1, [3 dc in next ch-1 sp, ch 1] twice, *[3 dc, ch 2, 3 dc] in next corner, ch 1, [3 dc in next ch-1 sp, ch 1] twice. Repeat from * around. Join and fasten off. (4 corners, 12 side clusters)
Round 4 (switch to Sage Green (B)): Join new color in any corner, ch 3, 2 dc, ch 2, 3 dc, ch 1. [3 dc in ch-1 sp, ch 1] to next corner. Repeat for all sides, joining at end. Fasten off. (4 corners, 16 side clusters)
Round 5 (switch to Cream (A)): Join in corner, repeat previous round sequence, working [3 dc in each ch-1 sp, ch 1 between clusters] along each side, and 3 dc, ch 2, 3 dc in each corner.
Continue to desired square size, alternating color order if you wish. For a 13 cm / 5 in square, 5 rounds are typical.

Attaching Butterfly

Position butterfly at the square’s center (RS up).
Sew down the butterfly body only, leaving wings free for a 3D effect, or lightly tack the inside edge if desired.

Making the Blanket

Make the desired number of squares (for example, 10 squares x 14 squares = 140 squares for 135 x 180 cm size).
Arrange squares with butterflies all the same direction, or rotate for a whimsical look.

Joining Squares

With Cream (A), using preferred join method (whip stitch or sc join), join squares row by row, then join rows together.
To join as you go: On the final round of each square, replace ch-1 between dc clusters with sl st to the corresponding place on the neighboring square.

Blanket Border

With Sage Green (B) or color of choice, work one round of sc around the blanket edge, working 3 sc in each corner.
Switch to Lilac (C) or Lavender (D) and work an hdc or dc round, placing 3 stitches in each corner.
Finish with a final round of cream in sc or a subtle decorative edge, such as picot or shell stitch, if desired.

Assembly and Finishing

After all squares are joined, weave in all remaining ends carefully using a tapestry needle, taking care at the backs of butterfly appliqués for a neat and secure finish. Lightly block the assembled blanket and individual squares if needed—pin into shape on a blocking mat and spray lightly with water or use a steam iron on low (if yarn allows), gently pressing but not flattening the butterfly wings. Allow to fully dry before use.

If making matching pillow covers, join squares as above and sew to the front of a plain cushion cover, leaving an opening for inserting the pillow. Add a zip or patch-style envelope closure to secure the pillow inside.

Check that all butterflies are securely sewn and wings are plumped up. Trim any visible yarn tails. Fluff and shape the butterflies for best 3D effect.

Customization Ideas

Swap colors for a pastel rainbow effect, bright summer shades, or monochrome elegance.
Make the butterfly in contrasting or variegated yarn for extra pop.
Use a bulkier yarn and bigger hook for a chunky winter throw, or lighter yarn for a baby blanket.
Create matching coasters, pillow covers, or a small baby lovey.
Arrange squares on a diagonal, use the butterfly motif for just the center blocks, or alternate with plain granny squares for less texture.

Troubleshooting

Curling: If your squares curl, your tension may be too tight or your hook too small. Loosen your grip or go up a hook size.
Uneven Edges: Consistent stitch count is key; count your clusters and spaces at each round.
Piece Too Large/Small: Check gauge before assembling squares and adjust hook size if needed.
Loose Color Changes: Fasten off securely, weave in ends at each change to prevent unraveling or holes.
Butterfly Wings Not 3D: Avoid sewing wings flat—only sew down the body, letting the wings remain free.
Uneven Tension: Block all pieces for uniformity and shape.

Care Instructions

Hand wash in cold or lukewarm water with mild detergent, especially if using cotton or delicate blends. Lay flat to dry, reshaping squares and butterflies as needed. Avoid wringing or heavy drying to preserve the 3D effect and color vibrancy. For best results, store folded with butterflies uncompressed.

Final Notes

Carefully count stitches on every round for consistency and alignment. Adjust your tension throughout to produce even squares. Refer to the photo as a visual cue for color placement, butterfly positioning, and border details. Enjoy the process; each unique butterfly square adds to a stunning handmade heirloom that brings joy with every use.
