Once you’re aware of all the creative possibilities, you’ll open up a whole new world for yourself in terms of completing your crochet work. Whether you’re joining granny squares or other motifs such as crochet pentagons, these joining methods will expand what you can create. Whipstitching is technically a sewing technique so for best results, you’ll want to use a tapestry needle with a large eye and a blunt tip to create this join. Anyone who is already familiar with hand sewing will have an edge up when learning this method of joining crochet. Even without experience, though, this proves to be an easy technique that you can learn quickly. You can use the same crochet hook you used to make the granny squares (or other pieces) you want to join. If you find it more comfortable to use another size (perhaps slightly smaller,) feel free, as long as you are easily able to achieve the same tension with the crochet hook you choose. Either way, you’re basically just working a slip stitch while holding two motifs together, working on the wrong side of the pieces to make a mostly invisible join. There’s a lot to absorb with this method; if you really want to understand the technique thoroughly, the best resource is Kristin Omdahl’s book, Seamless Crochet. There are also plenty of online resources for JAYGO.
