Crochet Bobble Stitch BABY BLANKET with Written Pattern. I’m here with you, with a new beginner blanket tutorial. Who doesn’t like to use bobble, puff, or popcorn stitches for a baby blanket? I love to crochet and use them. I think babies will love them too. Besides having a very nice texture, also suitable for use in both winter and spring. You can use cotton or wool, in any case, the blanket will look beautiful.
