Block of The Week: BLOCK 3: HALF DOUBLE CROCHET (Hdc)
The half double crochet stitch sits between single crochet and double crochet in height. It creates a fabric that is slightly taller than single crochet but more dense than double crochet.
The Half Double Crochet stitch combines elements of both single crochet and double crochet.
It is worked by:
1. Yarn over
2. Insert hook into the top loop of the stitch.
3. Yarn over, and pull through. You will have 3 loops on the hook.
4. Yarn over and pull through all three loops
Because the stitch is slightly taller than single crochet, the block will require fewer rows than Block 1.

Because half double crochet stitches are taller than single crochet but shorter than double crochet, this block uses fewer rows than Block 1 but more rows than Block 2.
Border Instructions
Ch 1.
Work single crochet evenly down the side of the block.
Try to crochet about 24–26 stitches along the side.
Corner:
Work 3 Sc in the corner stitch.
Continue around the block:
• Sc across the bottom
• 3 Sc in the corner
• Sc up the next side
• 3 Sc in the corner
• Sc across the top
Join to the first stitch.
Final Measurement
Your block should measure approximately:
8.5 inches x 8.5 inches
If your block is slightly smaller than expected, add one additional round of single crochet around the square.

1. Fasten off your yarn.
2. Use a yarn needle to weave in your ends.
3. Trim excess yarn.
