Mid-Century Modern Garter Block Throw with Reverse Single Crochet Border Free Pattern

Introduction

This Mid-Century Modern Garter Block Throw is a wonderful first blanket project for anyone who has mastered single crochet and wants to make something that looks far more complicated than it is. Each block is a simple flat square of single crochet, so you get plenty of relaxing, repetitive stitching before you ever have to think about joining. The palette of teal, rust, and cream gives it that warm, retro mid-century feel, and the mustard reverse single crochet border adds a raised, piped edge that makes the whole throw look polished and store-bought. Worked in worsted weight, it is dense, cozy, and sturdy enough to live on the sofa for years.

Materials Needed

• Yarn: Worsted weight (4) acrylic or cotton blend — Color A (teal) 600 yards, Color B (rust) 400 yards, Color C (cream) 400 yards, Color D (mustard) 200 yards
• Hook: 5 mm (H-8) crochet hook
• Notions: Tapestry needle for whipstitching and weaving in ends, scissors, stitch markers (optional), blocking mats and pins
• Finished size: 40 inches wide x 50 inches long

Abbreviations

• ch — chain: make a loop of yarn and pull it through the loop on your hook.
• sc — single crochet: insert hook into stitch, yarn over, pull up a loop, yarn over, pull through both loops.
• reverse sc — reverse single crochet (also called crab stitch): work a single crochet into the stitch to the right of your hook instead of the left, moving backward around the edge.
• sl st — slip stitch: insert hook, yarn over, pull through both the stitch and the loop on your hook.
• st(s) — stitch(es)

Gauge

16 stitches and 20 rows = 4 inches in single crochet. To check, crochet a small swatch and measure a 4-inch section in the middle; if you have more stitches than 16, go up a hook size, and if you have fewer, go down.

Tips Before You Start

• Make one test block first and measure it. Each block should finish at roughly 8 x 10 inches so that 5 blocks across give you 40 inches and 4 blocks down give you 50 inches.
• Keep your tension consistent from block to block — since the blocks are joined edge to edge, uneven squares will make the seams pucker.
• Label your finished blocks by color as you go, and lay them out on the floor before seaming so you can balance the teal, rust, and cream evenly.
• Practice reverse single crochet on a scrap swatch before starting the border; it feels awkward at first because you work backward, but it becomes rhythmic quickly.

Step-by-Step Instructions

Block (make 20: 8 in Color A, 6 in Color B, 6 in Color C)

Row 1: Ch 41, sc in 2nd ch from hook and each ch across (40 sc).

Rows 2-50: Ch 1, turn, sc in each st across (40 sc).

Fasten off. Repeat until you have 20 blocks: 8 in Color A, 6 in Color B, and 6 in Color C.

Assembly

Arrange the 20 blocks in 4 rows of 5, alternating colors evenly (for example, scatter the 8 teal blocks so no two sit side by side more than once, and balance rust and cream around them). Whipstitch the blocks together through the back loops only, joining blocks into rows first, then joining the rows to each other.

Border

Round 1: Join Color D to any corner. Ch 1, work reverse sc evenly around the entire perimeter, with 1 reverse sc in each stitch and 3 reverse sc in each corner. Join with sl st to the first reverse sc.

Round 2: Ch 1, reverse sc in each st around, working 3 reverse sc in each corner. Join with sl st. Fasten off.

Assembly and Finishing

Whipstitch all seams through the back loops only so the joins stay flat and tidy, then weave in every tail on the wrong side, threading each end through a few stitches before trimming. Block the finished throw by misting it lightly and pinning it to 40 x 50 inches on blocking mats, paying special attention to straightening the border; let it dry completely before removing the pins.

Pro Tips and Variations

• Swap the palette for any three mid-century colors — olive, burnt orange, and oatmeal work beautifully — and keep the mustard border for contrast.
• For a quicker version, work larger blocks (ch 61 and 70 rows) and arrange them in a 3 x 4 grid for the same finished size.
• Add a third border round in Color A for a two-tone piped edge, or work the final round in half double crochet for a softer, rounder finish.
