Equipment

• 1 Crochet Hook

Materials

  

• 1 skein SweetGeorgia Superwash DK
• 2 Granny squares

Instructions

 

• Start by laying out your squares in the pattern you prefer. 

  To connect them, we will be using the same stitch on both squares; in the video, this is the centre of chain 3, right at the square’s turning point. 

  Insert through the outside leg of each V stitch. When looking down, the top square’s V will point to the left, while the bottom square’s V will point to the right. 

  Start by inserting the hook into the top square’s right leg of the V.
  
• Now, go through the right leg of the bottom square’s V.
  
• Next, yarn over and pull through both legs to complete the setup.
  
• Once you’ve got that first stitch done, the rest is smooth sailing! 
  
• Now, we just have to repeat the process! Insert your hook into the top square, then the bottom square, pull through a loop, yarn over, and go through all three loops.
  
• It’s a rhythm you’ll get the hang of quickly. Most of the trick is knowing where to place your hook. Once that’s done, it’s just easy, breezy crochet joining from there!
  

Notes

Just keep an eye out for skipped stitches: if your squares don’t line up, check your last few joins, especially when you hit a chain one after a double crochet cluster, as it is a good place to stop double-checking your work for accuracy.
