Thank you so much for following along with our crochet plaid patchwork blanket CAL! It was so fun to see your progress and participation. Today we will use a simple method to sew the squares together into a finished blanket. This CAL is brought to you by Red Heart, all creatives, patterns and opinions are 100% my own. This post contains affiliate links, which means I get a small commission at no extra cost to you, thanks for your support!  

I hope you enjoyed making all the squares for this week.
I’m curious, did you like the graph squares? 

Today we need to sew everything together to complete the blanket. Take this part slow and pay attention to what you are doing. I had to pull out my first row no less than THREE TIMES because I was trying to crochet and watch HGTV at the same time.
Follow my instructions and hopefully you can learn from my mistakes!

Be sure you weave in all ends before sewing the squares together. Using a darning needle is the easiest way. 

1. Lay out your pieces the way you want them sewn together (it helps to take a photo with your phone or tablet so you can reference it later). The blanket will be sewn together in rows. My preferred method is sewing them together with a row of sc, but you can use your preferred method.

To do my preferred method, you will place the squares right sides together and sc in the back loops only of each square. Because they are right sides together, the back loops with be the loops on the outsides ( the loop closest to you and farthest from you).

The top of the seam will will look like this: (the back will have a ridge at the seam) 

2. Start with the bottom two rows. Make sure you have the two rows laid out the way you want. Once they are positioned correctly, take all the row 2 blocks and flip them each down on top of row 1. The blocks will be placed right sides together, and the row 2 blocks will appear to be upside down. (When you sew it together and flip it back up, it will be the right way!) Work one row of sc sewing across the 4 blocks (going through both squares)  They will look like a banner/garland, connected by only one stitch in between. 

(use this photo as a guide but notice my mountain was sewn on upside down, I had to pull it out!) 

3. Flip row 2 up and repeat the process when you sew row 3  to row 2, and when you sew row 4 to row 3. To avoid mistakes (I sewed it together wrong no less than 3 times!), make sure you lay it out correctly on the floor, flipping them down when you are ready to sew the next rows together. 

4. Your squares should be sewn into one piece, but all the vertical seams will be open. Sew the remaining seams row by row by folding the entire row over, working a long row of sc down the length of the blanket. Repeat this until all seams have been sewn together. 

Weave in all ends before making the border. 

5. This blanket would look great with any border, but I opted to do a simple row of DC around the outside. Join Charcoal anywhere and work DC around the outside. Make sure to work 4 dc in each corner. Join with first st and tie off. 

Well that’ a wrap on this FIRST week of Plaid Week.

  1. What should the length and width dimensions be following your pattern? I want to block my squares to prepare to assemble, my SO is going to make me my own wooden square to use to block them, but I need to know how big it has to be. Thank you in advance! I’ve had so much fun crocheting this blanket it will be the perfection addition to our baby boy’s nursery!

    1. Glad you like it!
      The finished size will depends your gauge, I suggest your foundation be 9″ long (so the finished will be about 9″ x 9″), so maybe block them to 10″. The gauge for blankets is not super important as it’s not a sized object, but I suggest making one square first to ensure the size of your exact squares. Does that make sense?

  2. My crochet matches your gauge, but you can see the yarn that I’m carrying between some of the stitches. How do I keep this from happening?
