Flat Slip Stitch Granny Join

Posted on Last updated: /

One of the ways that the granny squares can be joined together is by using the flat slip stitch. It produces lines that are flat but clearly defined, and these lines frame the squares. To this day, it remains one of my most favored granny square joins of them all.

Scroll down to the “How to crochet” section to learn how to join granny squares with a flat slip stitch, which I demo with solid granny squares.

This flat slip-stitch granny square join is how I joined the Sunburst Granny Square Blanket and Smiley Granny Bag (see pictures below). It makes vertical and horizontal lines that frame the squares that are flat and well-defined.

You may have also noticed that this method is similar to the slip-stitch join I used on the African Flower Purse, except that this flat slip-stitch method joins the squares from the front instead of the back.

There are many ways to join granny squares together. Choose the one that works best for your project. Here is a list of 12 ways to join your granny square. These are the most popular and often-used ways to join granny squares.

Materials

  • Granny Squares
  • Yarn (the same yarn weight that make your granny squares)

Tools

  • Crochet Hook

Instructions

  1. Granny squares (after blocked), crochet hook, and yarn for the joining. Use the same yarn and hook size that makes your granny squares.
    I used 4 squares in different colors and white yarn to join so that you can see the stitches clearly.flat slst joint 1


  2. a. Place the squares with the right side showing up as we are going to work on the right side of the square.
    b. Make a slip knot on the hook to begin, insert the hook into the back loop of the corner stitch of the first square, bring a loop out and make a slip-stitch.
    Note: If your squares have 2 chains at the corner (like mine), pick the chain stitch just before your first double crochet stitch on the edge that you are going to join.flat slst joint 2


  3. Insert the hook into the same back-loop corner stitch from front to back.flat slst joint 3


  4. Insert the hook into the back loop of the corner stitch of the second square, from front to back too.flat slst joint 4


  5. The white yarn should be always at the bottom of your work. Now, hook the white yarn and bring it up from the second square loop followed by the first square loop.flat slst joint 5


  6. Slip stitch to the first loop on the hook.flat slst joint 6


  7. Repeat the process on the second pair of stitches and so on.how to join granny


  8. Continue until you reach the corner stitch right after the last double crochet stitch on this edge.how to join granny


  9. Bring in squares 3 and 4, continue like the beginning of squares 1 and 2 except that you don’t have to make a slip knot onto the hook.flat slst joint 9


  10. Continue joining stitch on square 3 and 4 till the end.flat slst joint 10


  11. If you have more squares to join along the way, continue to do so until you reach the desired pieces of a granny square in the row. fasten off.
    Repeat the same to complete all the row seaming for the whole project before you proceed to join the column (vertical lines).flat slst joint 11


  12. Follow the same instructions when you do the column join until you reach the end of your first square.flat slst joint 12


  13. Make a chain stitch to cross over the row joint and repeat the same whenever you need to cross the following row joints.flat slst joint 13


  14. Continue with the normal flat slip-stitch until you reach the end. Fasten off.flat slst joint 14

Can one use the flat stitch joining for knitted squares?

It is possible, as long as you can pick up stitches from the edges of your knitted squares. Pay attention to the tension of the flat slip stitch so that it doesn't affect the length of the joins.

I have a friend who has approx. 136 granny strips but cannot figure out how to join them together on the ends. They are approx. 3 " wide and 6 " long. She says they bunch up when she tries to crochet the ends together. It is an older pattern and the pattern did not include how to put the ends together. Any help is appreciated. thank you...

Thank you for this post! I am making my first ever blanket with granny squares and it will be 17x25 (425 squares total!). I've been wondering how I will seam all those squares together. This method is very appealing and is likely what I will do in the end. Thanks!
