Earlier I put up a tutorial on how to crochet puff stitch. You might want to look at that and have a little practice before you start these puff stitch flowers. In her video Bella Coco shows you how to make the puff stitch flowers and at the end she shows how to sew them together so you can make bags, blankets, jackets. Whatever you want. Bees DIY has a free pattern for a puff stitch flower blanket and the instructions are clear and set out well. By changing the colour of your wool or yarn you can change the feeling of the blanket. You could make one for each season!
