Flat slip stitch joining is the ideal method of joining granny squares together.
If you are like me and love making granny squares but do not like stitching them up, there are many ways to do this and I think one of the easiest ways is with a slip stitch seam.
I feel it gives a more professional finish and look to it.
Below is a pictorial on how to do a sl st and how to seam the squares together.
This is the third pattern in my crochet afghan motif collection, if you are new to crochet and are looking for a quick project to practice with, granny square’s are ideal.
Turn them into blankets, throws etc. for your own home, friends, charities or fairs, many crocheters make these as they are a great way to use up all those odd ends of yarn that you have over from your other projects.
