Granny Square Sweater Tutorial – Using a Thrifted Blanket

Here is a trend to watch: the granny square sweater. When I saw this colorful blanket in the lonely aisles of a thrift store – i knew that it belonged in my arsenal. I love the way the intricate technicolor threads weave together to create an eye catching garment with a flash of vintage flair. These beauties take HOURS to make – which is why when I see a tattered blanket in the thrift store my heart just melts. I know that cutting into it will be its second purpose, and in a way, it will be restored to its former beauty.


All of you just loved this tutorial on a colorful granny square cardigan, which is why I’m sharing a similar tutorial that uses the unused bits of the blanket. This way, nothing goes to waste!


For this post, you’ll need a few things – all which you can pick up from your closet or a local thrift store:

I chose a knit weave for this project. I find that looser knit (bigger hole) sweaters are much harder to sew together. So, using a smaller knit will work best for this project.

InstructionsThere are multiple ways you can create this look – and none of the them are wrong! Basically, you can complete this vintage look with whatever method makes you most comfortable. The way I completed this project is the most advanced method. This includes cutting into the sweater and sewing the granny square in – this creates a sheer shoulder look. However, sewing the squares on top of the garment works just as well – you just wont have that peek-a-boo look.


Cut out a piece of granny square blanket to fit down the length of the sleeve. Each blanket is unique, mine is about 4 squares to the end of the sleeve.

Next cut from the top of the shoulder from the bottom of the sleeve. I also removed ~1-2 inches from each side of each slit in order to compensate for the fabric I would be sewing in.

Flip garment inside out. Pin and sew up both sleeves. I then sewed across the shoulder line in the inside of the garment to secure the top.

*If you do not feel comfortable with this technique, gluing using fabric glue also works wonders.  I recommend Beacon Fabric Glue*

    My family had one of these, which in New England we called "granny afghans." They always seemed to have a black crocheting around the colorful centers, which would go so well in this sort of project. I always loved the varied colors and don't know what became of that first one after I grew up and moved to another country, but for many years I kept another beautiful woolen granny afghan my grandmother had made for me to take to college, crocheted in dark blue, pink, and gray. When, some 48 years later, it was beginning to disintegrate, I didn't have the time to repair it, so gave it to GoodWill. Wish I had seen something like your DIY sweater back then!
