Crocheting a Circle Within a Square: A Fun and Creative Technique

Introduction
Crocheting a circle within a square is a fun and creative technique that adds an interesting twist to your crochet projects! By combining the softness of curves with the structure of corners, you can create unique and eye-catching designs. To start, work your square as usual, then switch to creating the circle in the center by gradually increasing your stitches.

The Pattern:
Ch 4 join in ring with a sl st.
Rounds Overview
Round 1: ch 3, 11 dc in ring, join with a sl st in first dc (12 dc if you will count the initial ch 3 as a dc stitch). Turn the piece – now you are working on the back side.
Round 2: ch 3, dc in same space, 2 dc in each of the next 11 stitches, join with a sl st in first dc (24 dc).
Round 3: ch 3, [dc in next st, (dc, ch 1, dc) in next st] - repeat 10 more times, dc in next st, dc in last stitch (from which comes the initial ch 3), ch 1, join with a sl st in first dc. That's it! Cut the yarn! The circle is ready! Don't forget to turn your piece because the right side is the first round facing you.
Transforming the Circle into a Square
Round 4: Let's turn our circle into a square! In this round, we are working in ch 1 spaces only, so you have to join a new color in any chain 1 space. There are a few ways to join yarn. I prefer the standing sc: make a slip knot and just work a sc in the desired space while holding the slip knot on your hook with your finger. Come about? Then make ch 2. So this sc and the ch 2 are made the initial dc stitch. Work 2 dc in the same space, ch 1, 3 dc in next space, ch 1, (3 treble, ch 2, 3 tr) corner made in the next space, ch 1, 3 dc in next space, ch 1 - repeat from this step 2 more times, then 3 dc in next space, ch 1, corner in next space, ch 1 and join with a sl st in the first dc (not in the initial stitch). Cut the yarn!
Completion
Ready! You got a lovely square with a cute small inner circle. Can you see the first round is the right side, the next two rounds are the wrong side, and the last square-round is again the right side?
