Using dp ndls and two strands,CO 8 sts. Join and knit one round. CONFUSED how do I join? Any help would be great. Thanks

Join is just knitting the stitch on the left needle. The working yarn will be on the right needle, then knit or purl the first st on the left needle. You might look at Advanceds Techniques for videos on knitting in the round, or at Knitpicks.

Here’s a favorite video for joining in the round without leaving a obvious bump.
