Alpine Stitch Fringed Crochet Blanket Pattern Free: Textured Diamond Post-Stitch Throw

If you love crochet throws with deep, architectural stitch definition that still drape smoothly across the sofa, the Alpine Stitch Fringed Crochet Blanket is one of the most rewarding patterns you can put on your hook. By alternating rows of plain single crochet on the wrong side with staggered front post treble crochet (trfp) and double crochet stitches on the right side, the fabric builds a rhythmic honeycomb of raised vertical diamonds—framed at both ends by crisp 3-inch single crochet borders and lush 3-strand knotted fringe.

Why the Alpine Stitch Works So Well for Marbled Throws

Heathered and marbled worsted yarns can sometimes obscure intricate lace, but the Alpine Stitch thrives on subtle marled color variations. Because every trfp reaches down two rows to wrap around the post of a double crochet stitch below, the raised vertical post catches the light while the single crochet return rows recess neatly behind it. Using a slightly generous 5.5 mm (US I/9) hook with #4 worsted yarn keeps the post-stitch fabric supple rather than stiff.

Materials & Custom Blanket Size Chart

To make the standard 50″ × 60″ living-room throw shown in the pattern, you will need:

• Yarn: 5 balls of Caron® Jumbo Marbled™ in Warm Wheat (74005) (or 2,686 yds / 2,456 m of any smooth #4 medium worsted acrylic yarn).
• Hook: Size U.S. I/9 (5.5 mm) crochet hook.
• Notions: Locking stitch marker (for marking the top border transition), blunt tapestry needle, tape measure, and sharp scissors for trimming fringe.

Because the Alpine Stitch pattern repeat uses a simple multiple of 2 chains + 4, you can easily resize this blanket for nurseries, reading chairs, or beds:

Step-by-Step Crochet Instructions

Part 1: Lower Single Crochet Border Band (3″ / 7.5 cm)

1. Foundation Chain: Ch 138 (or any multiple of 2 ch + 4).
2. Row 1 (WS): Work 1 sc in 2nd ch from hook. Work 1 sc in each ch to end of chain. Turn. (137 sc)
3. Row 2: Ch 1. Work 1 sc in each sc to end of row. Turn. (137 sc)
4. Build the Lower Band: Repeat Row 2 until work from beginning measures 3″ [7.5 cm], ending on a WS row.

Part 2: Main Alpine Stitch Blanket Body

Note: Ch 3 at the beginning of RS rows counts as the first dc throughout. Always skip the sc directly behind each trfp so your stitch count remains a steady 137 stitches on every row.

1. Row 1 (RS – Setup Row): Ch 3 (counts as first dc here and throughout). Work 1 dc in next sc, and 1 dc in each sc to end of row. Turn. (137 dc)
2. Row 2 (WS): Ch 1. Work 1 sc in each st to end of row. Turn. (137 sc)
3. Row 3 (RS – First Staggered Post Row): Ch 3. *1 trfp around next dc 2 rows below (in Row 1). 1 dc in next sc. Repeat from * to end of row. Turn. (137 sts)
4. Row 4 (WS): Ch 1. Work 1 sc in each st to end of row. Turn. (137 sc)
5. Row 5 (RS – Alternating Staggered Post Row): Ch 3. Work 1 dc in next sc. *1 trfp around next dc 2 rows below (in Row 3). 1 dc in next sc. Repeat from * until last st. Work 1 dc in last st. Turn. (137 sts)
6. Repeat for Length: Repeat Rows 2 to 5 for the Alpine Stitch pattern until work from the beginning measures approximately 57″ [144.5 cm], ending on a 5th row. Turn. Place a stitch marker (PM) at the beginning of this last row.

Part 3: Upper Single Crochet Border & Knotted Fringe

1. Next Row (WS): Ch 1. Work 1 sc in each st to end of row. Turn. (137 sc)
2. Complete Top Band: Repeat the last row until work from the stitch marker measures 3″ [7.5 cm] (bringing total blanket length to 60″ [152.5 cm]). Fasten off and weave in ends.
3. Knotted Fringe: Cut lengths of Warm Wheat yarn 14″ [35.5 cm] long. Holding 3 strands together for each bundle, fold in half and knot into fringe in every other stitch along both the top and bottom edges of the blanket. Trim fringe evenly across both ends.

Pro Tips for Crisp Alpine Stitch Tension

• Draw Up Your trfp Loops to Full Height: Because front post treble stitches reach two rows down, pull the initial loop up level with your current row before completing the three (yoh and draw through 2 loops) passes. This prevents the fabric from curling toward the front.
• Never Work Into Both the Post and the Top Loop: Each trfp replaces the single crochet stitch directly behind it. If you accidentally work into the sc behind the post stitch, your row count will increase rapidly.
