"The first seaming technique that most crocheters learn is the whipstitch. While whipstitching has a time and a place, there are several other types of seams used to join two pieces of crocheted fabric, such as the flat slip stitch seam. The flat slip stitch seam is my favorite crochet seaming technique that’s often used to join crocheted squares or hexagons for afghans. Aside from the whipstitch or mattress stitch, the flat slip stitch seam is one of the flattest seaming techniques used and when you use a contrasting color of yarn to work the seam it creates a visually stunning effect!"
