Plaid Patch Flip Flop Toppers: Free Crochet Pattern

Introduction

These Plaid Patch Flip Flop Toppers are the perfect little project for anyone who wants to dress up a plain pair of summer flip flops without committing to a full garment. They're made from four simple single crochet squares joined in a checkerboard of terracotta and mustard, which creates a cozy plaid-like patch that sits right over the strap area. Because the squares are flat and the stitches are basic, this is a genuinely beginner-friendly pattern — if you can chain and single crochet, you can make these. The finished toppers look crisp and a little bookish, with raised seam ridges that add texture and a dark academia feel to even the most casual sandals. They work up quickly, use only scraps of fine cotton, and make a lovely handmade gift or a satisfying weekend stash-buster.

Materials Needed

• Yarn: Fine (2) weight cotton — terracotta (A): 30 yd; mustard (B): 30 yd. This is enough for one pair of toppers with a little to spare.
• Hook: 4 mm (US G/6).
• Notions: Tapestry needle for seaming and weaving in ends, scissors, and a pair of standard flip flops to attach the toppers to.
• Finished size: Each topper measures about 2.5 inches wide x 3 inches long and fits a standard flip flop strap area.

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.
• st(s) — stitch(es): the loops you work into.
• WS — wrong side: the back face of the fabric.
• R — row.

Gauge

5 stitches and 5 rows = 1 inch in single crochet. To check, work a small swatch in sc and measure a 1-inch section; adjust your hook size if you're getting more or fewer stitches than that, since the squares depend on it for the finished size.

Tips Before You Start

• Keep your tension even and slightly firm — loose single crochet squares can stretch out of shape once they're sewn onto the flip flops.
• Make all four squares first and lay them out in the checkerboard (A B / B A) before joining, so you can confirm the color placement.
• When joining squares, work through both layers with the wrong sides together so the seam ridges sit on the right side for that plaid look.
• Leave a generous tail on the strap covers — you'll use it to sew them down and to attach the topper to the flip flop.

Step-by-Step Instructions

Square (make 4: 2 in A, 2 in B)

Row 1: Ch 13, sc in 2nd ch from hook and each ch across (12 sc).

Rows 2–12: Ch 1, turn, sc in each st across (12 sc).

Fasten off. Each square measures about 2.4 inches square.

Join Squares

Arrange the four squares in a checkerboard: A B on top, B A on the bottom.

Horizontal joins: With A, hold the top two squares WS together and sc through both layers across one edge (12 sc). Repeat for the bottom pair (12 sc).

Long-edge join: Hold the two joined pairs WS together along their long edges and sc through both layers with A (24 sc). Fasten off.

Strap Cover (make 2)

Row 1: With A, ch 5, sc in 2nd ch from hook and each ch across (4 sc).

Rows 2–10: Ch 1, turn, sc in each st across (4 sc).

Fasten off, leaving a long tail. Each cover measures about 0.8 inch x 2 inches.

Assembly

Center one strap cover over the joined squares, aligning its long edges with the patch's long edges. Using the tail, sew the strap cover to the squares along both long edges. Repeat for the second topper.

Attach to Flip Flops

Place a topper over the flip flop strap area, centered. Using matching yarn, sew through the strap cover and around the flip flop strap at several points to secure it. Repeat for the second flip flop, then weave in all ends.

Assembly and Finishing

All seaming is done with A and a tapestry needle, working along the long edges of the strap covers and through the strap of the flip flop. Weave in every end on the wrong side, taking care not to pull the fabric out of shape. Lightly mist the finished toppers with water and press flat under a cloth, or pin them to shape and let them dry fully before attaching — cotton single crochet benefits from a gentle block to keep the squares crisp and even.

Pro Tips and Variations

• Swap the colors for a different palette — navy and cream, or olive and rust, keep the plaid feel while changing the mood.
• Add a simple sc border around the outer edge of the joined patch in A for a more finished, framed look.
• For a sturdier topper, work the strap cover in a slightly tighter gauge or add a second row of sc along its long edges before sewing down.
