Hi, thank you for asking. ☺️ When you're crocheting in the round, you typically don't need to turn your work. Turning your work is usually done in projects that are worked in rows, not in the round.
Hi, thank you for sharing your experience. In this case, it seems like you may have overlooked the last space where you slip stitched in the previous round, which could result in an additional stitch. I suggest using a stitch marker to mark the last stitch to prevent accidentally adding an extra stitch in that space 😃
In this video, I don't count the chain 3 as the first stitch. I place 2 double crochets into the same stitch where I slipped stitch last round and count that as 2 stitches. However, if you prefer counting the chain 3 as the first stitch, you can make 1 double crochet into the same stitch and count that as 2. Feel free to choose the method that works best for you! Happy crocheting!😃
