📌 Before You Begin

💡

This pattern uses advanced pineapple clusters arranged in a grid layout. Familiarity with post stitches and cluster work is required.

💡

Pineapple motifs are created by working treble clusters around post stitches to form dimensional diamond shapes.

💡

Blanket is worked in rectangular sections joined together; this modular approach ensures even tension and easier handling.

💡

Sport weight yarn provides appropriate drape for a picnic blanket without excess weight.

💡

Use stitch markers to track the beginning of each pineapple repeat row.

🧶 Pattern Instructions

💡 Tip: Count your chain carefully; miscounting will affect the pineapple alignment throughout.
  1. Row 1
    Ch 241. Sc in 2nd ch from hook and in each ch across (240 sts). This creates your foundation width of 48 inches.
Row counter:
💡 Tip: Keep post stitches tight and vertical for dimensional pineapples. This row stabilizes your clusters.
  1. Row 2
    Ch 1, sc in each st across (240 sts). This is your anchor row.
  2. Row 3
    Ch 3 (counts as dc), sk 1 st, *[tr, ch 1, tr] in next st (pineapple start), sk 1 st, dc in next st, sk 1 st, rep from * across, ending with dc in last st (60 pineapple clusters spaced across).
  3. Row 4
    Ch 1, sc in base of ch-3, sc in each st and ch-sp across, sc in top of turning ch (240 sts).
Row counter:
💡 Tip: The pineapple clusters grow larger with each cycle. Ensure consistent tension so clusters remain uniform.
  1. Rows 5, 8, 11, 14 (Pineapple Build Rows)
    Ch 3, sk 1 st, *sc in next st, sc in next st, [tr, ch 1, tr] in next st (pineapple expands), sc in next st, sc in next st, dc in next st, sk 1 st, rep from * across, ending with dc in last st (240 sts). Work post stitches around the chain-1 spaces from previous pineapple rows for dimensional effect.
  2. Rows 6, 9, 12, 15 (Anchor Rows)
    Ch 1, sc in each st and sp across (240 sts).
  3. Rows 7, 10, 13, 16 (Decrease Rows)
    Ch 3, sk 1 st, *[tr, ch 1, tr, ch 1, tr] in next st (pineapple peak), sk 2 sts, dc in next st, sk 1 st, rep from * across, ending with dc in last st (240 sts). These rows create the diamond peak of each pineapple motif.
Row counter:
  1. Rows 17-24
    Ch 1, sc in each st across (240 sts). Work 8 rows of single crochet to create a solid band that visually separates the pineapple grid from the bottom section and provides weight for the blanket to drape properly.
Row counter:
💡 Tip: Mirroring the top section creates visual balance and ensures even weight distribution.
  1. Rows 25-40
    Repeat the pineapple expansion sequence (Rows 3-16) to create a symmetrical blanket. Work pineapple build rows, anchor rows, and decrease rows in the same pattern and order as the top section (240 sts maintained throughout).
Row counter:
💡 Tip: The shell edging adds a delicate frame and prevents the blanket edges from curling.
  1. Round 1 (Edging Setup)
    With RS facing, join yarn to any corner st. Ch 1, sc evenly around entire blanket perimeter, working 3 sc in each corner st to maintain flat edges. Approximately 480-500 sc around. Sl st to join.
  2. Round 2 (Shell Edging)
    Ch 1, sc in same st, *sk 2 sts, [2 dc, ch 2, 2 dc] in next st (shell), sk 2 sts, sc in next st, rep from * around, adjusting spacing to fit corners with 5 dc in corner sts. Sl st to join.
  3. Round 3 (Picot Trim)
    Ch 1, sc in each st and sp around, working [sc, ch 3, sc] in each ch-2 sp (picot). Sl st to join and fasten off (approximately 520 sts).

✂️ Finishing

Weave in all ends carefully on the WS using a tapestry needle. Block the finished blanket gently by laying it flat on a clean surface, misting lightly with water, and allowing to air dry completely. This evens out the pineapple motifs and creates gentle drape. Once dry, fold or roll the blanket for transport; the lightweight sport yarn makes this ideal for picnics.

🧺 Care Instructions

Hand wash in cool water with gentle detergent. Rinse thoroughly until water runs clear. Gently squeeze out excess water without wringing. Lay flat or hang to dry away from direct sunlight and heat. The cotton-blend yarn may require light blocking after each wash to maintain the pineapple definition.

Questions About This Pattern

Absolutely — just match the weight (Sport). You'll need about approximately 1800 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 ch, sc, dc, tr 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.
Find the stitch repeat in the pattern (usually mentioned in the foundation chain section) and add or remove multiples of that number. Keep in mind: with Sport yarn, every extra inch of width across a blanket adds meaningful yardage — double the size means roughly 4× the yarn. For a baby blanket, halving the dimensions works well as a starting point.
For this pattern, gauge is "20 sc x 22 rows = 4 inches in single crochet (used for edging measurement)". 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 gentle detergent. Rinse thoroughly until water runs clear. Gently squeeze out excess water without wringing. Lay flat or hang to dry away from direct sunlight and heat. The cotton-blend yarn may require light blocking after each wash to maintain the pineapple definition. 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.
Each section builds on the last, so yes — follow them in order. That said, some finishing sections (like embellishments or optional edging) can be skipped if you prefer a simpler look. Read through all sections before starting so you understand how the pieces fit together and can plan your yarn usage across sections.
