Autumn Granny Square Book Sleeve Free Crochet Pattern

Introduction

This autumn granny square book sleeve is the perfect quick project for anyone who loves curling up with a paperback and a mug of something warm. It's made from just two solid granny square panels in forest green and rust, so it looks cozy and seasonal while being wonderfully simple to crochet. The dense double crochet fabric feels soft but sturdy, giving your book a snug, protective hug, and the button loop keeps everything neatly closed in your bag. Even if you've only ever made a basic granny square, you'll find this beginner-friendly pattern easy to follow from start to finish.

Gauge

1 granny square = 5" (12.7 cm) square after blocking. Work one panel through Round 12 and measure it flat; if it's larger or smaller, adjust your hook size to match.

Tips Before You Start

• Keep your tension even on the corner increases — the (2 dc, ch 2, 2 dc) groups are what keep the square flat, so don't pull them tight.
• Count your stitches at the end of each round; each round adds 16 dc, so the totals should climb 12, 28, 44, 60 and so on.
• Block both panels before joining so the squares match in size and the finished sleeve sits flat.
• Leave generous yarn tails when you fasten off — you'll use them to weave in securely later.

Fasten off. Weave in ends. Repeat for the second panel.

Assembly

Place the two panels with RS together. Join with Color A using sc through both layers: work sc evenly along three sides (left, bottom, right), working 1 sc in each dc and 1 sc in each ch-2 sp. Fasten off.

Edging

Turn work RS out. Join Color B with sl st to the top right corner. Ch 1, sc evenly around the entire opening, working 1 sc in each st and 1 sc in each row end. Join with sl st to first sc. Fasten off.

Button Loop

Join Color B with sl st to the top center of the back panel. Ch 12, sl st to same st to form a loop. Fasten off. Sew the button to the front panel opposite the loop.

Assembly and Finishing

Weave in all remaining ends securely on the wrong side, taking care to hide the tails from the assembly seam and edging. Block the finished sleeve lightly to measurements (approx. 10" x 15" / 25.5 x 38 cm) by misting with water and pinning flat to dry — this smooths the edges and helps the panels sit evenly. Once dry, slip a paperback inside to check the fit and adjust the button if needed.

Pro Tips and Variations

• Color play: Work each panel in a different color, or add a contrasting final round to each square for a striped border effect.
• Size it up: Add extra rounds to both panels to fit larger hardbacks or tablets — just remember to add the same number of rounds to each panel.
• Sturdier closure: Use a slightly larger button or add a second loop for a more secure, adjustable fit.
