Bobble Stitches (often abbreviated as “bo”) are actually one of my most used stitches in crocheting. That might sound surprising, but in Amigurumi, stitches adding height like a double and triple crochets just end up leaving big holes to let out the stuffing. Where as a well placed bobble stitch can be used to features like noses, toes, and and even limbs without having to make them separately and sew them on.
I use bobble stitches mostly to add features to my amigurumi, but they can also be used in blankets, or hats, really anywhere that you want to add just a little bit more texture to your project.
