How do you measure tension in crochet?
Use a pin as a marker and insert it vertically between two stitches. Then, using a rigid ruler, horizontally measure 10cm (4in) and place another pin in the fabric. Count the number of stitches between the two pins and if your tension corresponds with that given in the pattern, then you can start crocheting.
What is a crochet ring?
The center ring is the foundation for all crocheted designs that are worked in rounds — just like the foundation chain you use when working in rows. … The center ring is the circle created by several chain stitches joined together to form a circle, or it can be just a single chain stitch.
