Welcome to the world of crocheting!
When a pattern refers to ‘the next stitch’ it may be a chain or it may be something else, depending on what was done in the previous row. If it is a chain, it is usually referred to as ‘the next chain’ though.
With the chevron pattern that you mention, to begin row 2, you would do 1 chain then do 2 single crochets into ‘the next stitch’ which is the last stitch of the previous row. the turning chain 1 does not count as ‘the next stitch’. Then you would work a single crochet into each of the next 4 stitches, which I am assuming are single crochets from the previous row since the beginning chain is not usually referred to as row 1.
Then you skip the next two stitches which serves to draw up the work to form the ‘valley’ of the chevron. Then single crochet into each of the next 4 stitches.
then work 3 single crochets all into the next stitch which forms the ‘peak’ of the chevron.
So if the Row 2 you are talking about is indeed the second row AFTER the beginning chain, you will be working all your stitches into the single crochets of Row 1. Row 1 would be similar, but would be worked into the CHAINS of the beginning chain.
Oh boy, I hope I didn’t confuse you even more! If you are interested in working this particular pattern and can’t find a video to help you, let me know and I’ll work one up and post it on my website. I’ve done many for knitting and crocheting, a few of them by request of people here on knittinghelp.com for patterns they were having trouble with.
Crocheting is fun, so don’t give up! Let me know if I can help!
