Need help understanding part of pattern instructions
I'm hoping someone here can explain to me what this instruction means for this pattern because it keeps tripping me up. I'll highlight the really confusing part:
Sc in second ch from hook, sc in each of the next 20 ch; 3 sc in last ch, working across opposite side of foundation ch, sc in remaining loop of each of next 20 ch, sc in next ch already holding 1 sc, sl st to the first sc to join--46sc.
If anyone can explain that to me, it would be a great help.
Thanks in advance...
