📌 Before You Begin

💡

This pattern creates 16 individual 8-inch granny squares in asymmetric color arrangement. Plan your color layout on paper before beginning.

💡

Each square uses exactly 2 colors (Rounds 1-2) or 3 colors (if you introduce a third color in Round 3). Most crafters will use 2 colors per square; use 3 colors only when intentionally adding a contrasting Round 3. This ensures balanced color distribution across the 4x4 grid.

💡

Advanced techniques include color changes mid-square, strategic yarn placement, and professional blocking with dimensional shaping.

💡

Join squares using whip stitch or mattress stitch (see abbreviations for definitions) for invisible seams. Do not use slip stitch joins as they create visible ridges.

💡

Weave in ends as you work to minimize finishing time.

🧶 Pattern Instructions

💡 Tip: Rotate color placement for each square. Create a color map showing which 2-3 colors go in each square position before beginning to ensure asymmetric but balanced distribution across the 4x4 grid.
  1. Round 1
    With first color, ch 4. Sl st to form ring. Ch 3 (counts as first dc), 2 dc in ring, ch 2, [3 dc in ring, ch 2] 3 times. Sl st to top of ch-3. (12 dc, 4 ch-2 sps)
  2. Round 2
    Cut yarn leaving 6-inch tail. Attach second color to any ch-2 sp with st">sl st. Ch 3, 2 dc in same sp, ch 2, 3 dc in same sp (corner made). Ch 1, [3 dc in next ch-2 sp, ch 2, 3 dc in same sp, ch 1] 3 times. Sl st to top of ch-3. (24 dc, 4 corners with ch-2, 4 ch-1 sps)
  3. Round 3
    Cut second color. Attach third color to any ch-1 sp. Ch 3, dc in same sp, ch 1, (2 dc, ch 2, 2 dc) in next corner ch-2 sp, ch 1, [2 dc in next ch-1 sp, ch 1, (2 dc, ch 2, 2 dc) in corner, ch 1] 3 times. Sl st to top of ch-3. Fasten off leaving 12-inch tail for sewing. (48 dc total: 8 dc per corner × 4 corners = 32 dc, plus 2 dc in each of 8 ch-1 sps = 16 dc; 4 corner ch-2 sps, 8 ch-1 sps)

💡 Tip: For invisible seams, practice whip stitch or mattress stitch on scrap fabric first. Insert needle directly into the edge loops without catching interior stitches.
  1. Step 1: Block Individual Squares
    Lay each finished square on blocking board. Pin corners at right angles. Using cool water and light steam or blocking spray, gently shape each square to exact 8-inch measurements. Allow 24 hours to dry completely.
  2. Step 2: Plan Layout
    Arrange 16 squares in 4x4 grid on flat surface. Position so colors flow asymmetrically but create visual balance. Take a photo for reference during sewing.
  3. Step 3: Sew Squares Together
    Using whip stitch or mattress stitch and color-matched thread, join squares as follows: First, join 4 squares horizontally (left to right) to form a row using 3 seams. Repeat for remaining 3 rows, creating 4 horizontal strips. Then, join the 4 strips together vertically (top to bottom) using 3 seams. Keep seams invisible by inserting needle between outer loops only. Weave in any remaining ends.
  4. Step 4: Final Blocking
    Pin completed wall hanging to blocking board, stretching gently to 32 inches square. Steam lightly and allow to dry 48 hours. This sets the seams and ensures a professional finish.

✂️ Finishing

After all squares are sewn and final blocking is complete, weave in any remaining yarn tails. If desired, block again under light tension to ensure the finished piece lies perfectly flat. The wall hanging is now ready for mounting. For display, use small adhesive hooks or a fabric strip sewn to the back edge for hanging on walls or over furniture.

🧺 Care Instructions

Hand wash in cool water with mild wool detergent. Do not wring. Lay flat to dry. Block again every 6-12 months to maintain shape and dimension. Avoid direct sunlight to preserve color vibrancy, particularly in the gold, rose, and coral shades. Store rolled (not folded) on acid-free tissue paper.

Questions About This Pattern

Absolutely — just match the weight (Sport). You'll need about approximately 1200 yards, so make sure your substitute has enough meterage. Fine yarns give delicate detail. Cotton is great for structured pieces; mohair adds a halo effect for a dreamy look.
This pattern uses techniques that require precision and experience. Expect stitches like sc, ch, sl st, dc and potentially complex shaping. If you're newer to crochet, try a few intermediate patterns first to build confidence with stitch counts and tension before tackling this one.
Usually it's the joining or finishing — where individual sections meet and need to align. Read through the entire pattern once before you start so there are no surprises. Use stitch markers generously to track your place, especially in rounds. If a section looks wrong, count your stitches before proceeding — catching an error early saves a lot of frogging later.
For this pattern, gauge is "18 sc x 18 rows = 4 inches in single crochet". For decorative or non-fitted items it's less critical, but matching gauge ensures you use the right amount of yarn and get the proportions the pattern intends. If your swatch is too small (too many stitches/inch), go up a hook size. Too large — go down.
Hand wash in cool water with mild wool detergent. Do not wring. Lay flat to dry. Block again every 6-12 months to maintain shape and dimension. Avoid direct sunlight to preserve color vibrancy, particularly in the gold, rose, and coral shades. Store rolled (not folded) on acid-free tissue paper. A general rule: when unsure about the yarn, hand wash in cool water with a drop of gentle detergent, squeeze (don't wring), and block flat to dry. This is safe for almost every fiber.
