Crochet T-Shirt Yarn Square
Welcome to this beginner-friendly pattern where we create a beautiful crochet square using soft t-shirt yarn and single crochet stitches. This project is ideal for upcycling your t-shirt yarn and makes sturdy coasters, afghan blocks, or patchwork for bags and rugs. Follow along for all tips, tricks, and step-by-step guidance—let’s get started together!
Quick Overview Of the Pattern
In this project, you will make a square using t-shirt yarn worked in the round. Beginning with a magic ring, you build the square by placing sets of single crochets at the corners each round, with straight edges between. Unique to this method, you will use an “invisible slip stitch” to finish each round—giving a neat, seamless finish.
Notes
- Worked in rounds: This project is constructed in joined rounds, not spirals.
- Magic ring start: This ensures a snug, hole-free center.
- Invisible slip stitches: These replace a standard join for an almost invisible seam. See the Special Stitches section for how it’s done.
- Growth: Each round, the square is made larger by increasing the number of single crochet between the corners.
- If you want a bigger square, simply continue adding rounds.
- Instructions use the same color throughout, but you can change colors for each round if desired.

Special Stitches
Magic Ring (MR):
Make a loop; work the indicated number of stitches into it, then pull the tail to close.
Invisible Slip Stitch Join:
- After completing the round, remove your hook from your loop.
- Insert hook (front to back) into the second sc of the round.
- Pull your working loop through the stitch (sl st).
- Insert your hook again into the first stitch, pick up the loop, and pull through.
This join makes seams almost invisible. See video tutorials for help if needed.
The Crochet Pattern
Round 1: Center
- Make a magic ring (MR).
- Chain 1.
- Work 7 sc into the MR. (Count: 7 sc)
- Pull the tail tightly to close the ring.
- (Invisible slip stitch join) Remove your hook from the working loop, insert hook (front to back) into the first sc, draw the loop through, then insert the hook into the next stitch and pull loop through. This completes the round seamlessly.
Round 2: Making the Square
- The loop on your hook now counts as your first sc of the round.
- In the next stitch, work 3 sc in the same st (corner).
- In the next stitch: 1 sc.
- In the next stitch: 3 sc in the same st (corner).
- In the next stitch: 1 sc.
- In the next stitch: 3 sc in the same st (corner).
- In the next stitch: 1 sc.
- In the last stitch: 3 sc in the same st (corner).
Finish with invisible slip stitch:
- Remove your hook, insert into the second sc of the round, pull through loop, then into the first stitch and pull through again.
At this stage, you have a 4-sided figure (square) with 3-sc groups at each corner.
Round 3: Growing the Square
- The loop on your hook is your first sc of the round.
- Next st: 1 sc.
- Next st: 3 sc in the same st (corner).
- Now, work 1 sc in each of the next 3 sts.
- Next st: 3 sc in the same st (corner).
- Now, 1 sc in each of the next 3 sts.
- Next st: 3 sc in the same st (corner).
- 1 sc in each of the next 3 sts.
- Next st: 3 sc in the same st (corner).
- 1 sc in each of the last 2 sts.
Finish with invisible slip stitch as before.
Round 4: Square gets larger
- The loop on your hook is your first sc.
- Next 2 sts: 1 sc in each (now 3 sc total).
- Next st: 3 sc in the same st (corner).
- 1 sc in each of the next 5 sts along the side.
- Next st: 3 sc in the same st (corner).
- 1 sc in each of the next 5 sts along the side.
- Next st: 3 sc in the same st (corner).
- 1 sc in each of the next 5 sts along the side.
- Next st: 3 sc in the same st (corner).
- 1 sc in each of the next 2 sts to finish the round.
End with invisible slip stitch as in previous rounds.
Tip:
To make your square bigger, continue the established pattern:
- Each round, your sides increase by 2 sts between corners.
- The four corners are always 3 sc in the same stitch.
- The “side” sections between corners will always be an odd number and will grow with each new round.
Assembly & Finished Size
No assembly needed! Weave in any ends. Block gently if you’d like your square to lay completely flat (especially recommended for t-shirt yarn, which can curl slightly).
- After 4 rounds, your square will measure about 10 cm (4 inches), but you can easily make it larger.
Conclusion & Ending Words
You have now mastered the crochet t-shirt yarn square—an excellent skill for beginners and a foundation for many projects like blankets, bags, and coasters. This straightforward design can be expanded by adding as many rounds as you wish. Use different colors for a playful patchwork, or stick to one shade for a modern, minimal look.
