Project Overview

This blanket is composed of multiple log cabin-inspired granny squares, each built in rounds using clusters of double crochet stitches. The blanket and pillow covers are constructed by joining these squares together with a visible, neat joining technique. Each square is made in alternating lavender and cream sections, forming an off-center, step-like motif. Once the squares are completed and joined, a wide granny-style border is added for a polished finish.

The construction process is modular, making this project highly portable and easy to customize in size. The squares are crocheted individually and then joined together, followed by a border to unify the finished piece.

Skill Level

Advanced Beginner. You should be comfortable with basic crochet stitches (chain, slip stitch, double crochet) and working in rounds. Some experience with joining motifs and changing colors neatly is helpful, but detailed instructions make this a rewarding project for adventurous beginners too.

Materials

Yarn: Worsted weight (category 4) yarn. Acrylic or cotton-acrylic blends work very well for durability and softness. For a full queen-sized blanket (30 squares, plus 4 for pillows):
- Lavender: Approx. 1,200 yards (1,100 meters)
- Cream: Approx. 1,800 yards (1,650 meters)
Crochet Hook: Size H-8 (5.0 mm) or size needed to obtain gauge
Tapestry Needle: For weaving in ends and sewing squares together
Scissors
Stitch Markers: Helpful for marking corners or the start of rounds
Measuring Tape

Choose a smooth yarn for best stitch definition, and consider using anti-pilling yarn if the blanket will be used frequently or laundered often.

Finished Size

The finished blanket is approximately 210 cm x 210 cm (82 in x 82 in), assuming you join 36 squares (6 x 6) for a queen-sized bed. Each square measures about 35 cm (13.75 in) across after blocking. To adjust the blanket size, simply add or subtract squares, or adjust the number of rounds in each square. Pillow covers are typically made with one square each, finished to 43 cm (17 in) with a border.

Gauge

Approximate gauge: Each completed square before joining (unblocked) should measure about 32 cm (12.5 in) per side. Gauge is not critical for this project, but keeping all squares consistent in size is essential for neat assembly. Adjust hook size if your squares differ greatly from these measurements.

Stitches and Abbreviations

ch: chain
sl st: slip stitch
sc: single crochet
dc: double crochet
sp: space
st/sts: stitch/stitches
beg: beginning
RS: right side

Pattern Notes

All instructions use US crochet terminology.
Ch 3 at the start of each dc round counts as the first dc unless otherwise specified.
Squares are worked in joined rounds, turning at the end of each round for a neat look.
Change colors at the end of a round: finish the last dc with the new color and continue in pattern.
Mark corners, especially as the motif grows, to ensure the placement of increases is consistent.
Keep your tension even; if your squares curl or ruffle, adjust your hook size or tension as needed.
Weave in ends as you go, especially when changing colors frequently, to minimize finishing work.

Crochet Pattern Instructions

Main Granny Log Cabin Square

With lavender, ch 4, sl st to first ch to form a ring.
Round 1 (Lavender): 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. (12 dc, 4 ch-2 corners)
Round 2 (Lavender): Ch 3, 2 dc in same sp, ch 1, [3 dc, ch 2, 3 dc] in next ch-2 corner, ch 1, (3 dc in next space, ch 2, 3 dc in same sp) three more times, ch 1, join with sl st to top of beg ch 3. Turn. (24 dc, 4 ch-2 corners)
Round 3-4 (Lavender to Cream): Continue as established: For each side, (3 dc, ch 1) in each space, and (3 dc, ch 2, 3 dc) in each corner. Change to cream at Round 4 by joining new yarn in the corner. Complete two rounds in cream in the same manner. (Each round increases the number of 3-dc clusters per side by 1)
Round 5-6 (Lavender): Continue with two more rounds in lavender, working (3 dc, ch 2, 3 dc) in corners, (3 dc, ch 1) in each space across sides. Fasten off and join cream in any corner to shift colorwork.
Round 7-8 (Cream): Repeat as before, working two cream rounds. The square should now have an L-shape color change twice per color, forming the log cabin steps. If following this block structure, you can continue with alternating two rounds per color, always ending in cream for bold definition, until your square measures approximately 35 cm (13.75 in). Add or reduce rounds to match desired size.

Joining Squares

Arrange finished squares in a 6 x 6 grid (or as desired for your blanket size). Lay out the color orientation for a harmonious pattern—alternate the lavender step direction for a dynamic visual effect.
With cream, use single crochet or slip stitch to join squares together through the back loops only for a raised, dimensional join. Work row by row, then column by column, keeping squares aligned at corners.

Border

With cream, join yarn in any outer corner.
Round 1: Ch 3, 2 dc in same sp, ch 2, 3 dc in same sp (corner made), *[ch 1, 3 dc in next ch-1 sp]* around, placing (3 dc, ch 2, 3 dc) in each outer joining point (corner), join with sl st to top of beg ch 3. Turn.
Rounds 2-4: Repeat round 1 as established around the full blanket, adding rounds until the border reaches approx. 8 cm (3 in) for a wide, finishing effect. Fasten off and weave in ends.

Pillow Covers (Optional)

Make two squares as for blanket, add extra border if needed to cover pillow form. Join two squares (or one square and a solid crochet back) with single crochet in cream, inserting the pillow at the last seams. Optionally, add buttons along one side for easy removal.

Assembly and Finishing

Before joining, block each square gently to ensure they are uniform in size and lay flat. Pin to shape (dampen and lay on a towel, or use steam blocking on acrylic). For assembly, use a single crochet (sc) or slip stitch seam in cream yarn, working through the back loops to create well-defined ridges between motifs. Double-check that edges and corners align. Once all squares are connected, weave in all yarn tails carefully using a tapestry needle, taking care to secure color joins. Add the border evenly around the outer edge, working granny clusters and corners for continuity. Block the blanket again after completing the border for the best drape and finish. For pillow covers, sew or crochet the sides together, insert pillow forms, and add fastenings if desired. Keep the finished blanket folded or draped to maintain its beautiful shape.

Customization Ideas

Colors: Swap lavender for any favorite color—dusty rose, light mint, or serene blue. Use a deeper neutral such as grey or taupe instead of cream for a more modern look.
Yarn Types: Use chunky yarn for a heavier winter throw, lightweight cotton for a cool summer blanket, or ombre yarn for a gradient effect.
Arrangement: Lay out squares in different orientations—have “steps” facing inward, outward, or random for unique designs.
Uses: This motif works beautifully for baby blankets (just use fewer motifs), throws, wall hangings, or cushion covers.

Troubleshooting

Curling Squares: Curling may result from tight tension or too-small hook—switch to a larger hook or consciously relax your tension. Block squares if curling persists.
Uneven Edges: Ensure consistent stitch counts on each side, especially in corners, and avoid skipping spaces. Use stitch markers in corners as guides.
Blanket Too Large/Small: Double-check gauge before starting. Adjust by changing hook size or number of rounds.
Color Changes Loose or Noticeable: Always finish the last yarn-over of the final dc of a color section with the new color for seamless transitions. Weave in ends securely at color changes.
Uneven Tension Across Squares: If your tension changes mid-project, your squares may vary in size. Pause to do a quick measurement every few squares and adjust as necessary.

Care Instructions

Hand or machine wash your finished blanket gently according to yarn label instructions. Use cool water and mild detergent. For best results, lay flat to dry to prevent stretching. Store folded or draped—avoid hanging, as this may distort the piece over time. If blocking is needed after washing, reshape gently with pins as before.

Final Notes

Take your time to check stitch counts and square sizes frequently to ensure a professional finish. Adjust your tension if you notice significant size variation. Use the project image as a visual guide for color order and square placement, and don’t be afraid to experiment. With dedication, this blanket will become a beloved, eye-catching addition to your home or a treasured handmade gift!
