How to join granny squares with an invisible seam

There are many different joining techniques for afghan and granny squares. One of the most popular is the ‘invisible seam‘ method. This technique creates a flat seam which is invisible. It will look like the squares are glued together at the edges. This method is especially useful for joining squares with different colors. Below you can find my photo and video tutorialย of the invisible seam for joining squares, such as afghan and granny squares.

Tips and tricks on joining granny squares withย an invisible seam

Before you start, cut yarn about two times the length of the side you want to sew. This way you’ll have enough yarn for joining and weaving in the ends. Use a yarn color that matches at least one of the squares. Even if the other square is a different color, don’t worry. As the name says, this joining method is invisible, so you won’t see it at all.

Make sure the stitches of both squares are aligned. If you’re working with different squares that don’t have the same amount of stitches, it’s easier to use pins or stitch markers to keep the squares together nice and even. Also, make sure to pull tight as you go. If you wait till the end, you will notice it will be more difficult.
