2 strand knitting help!

I’ve justed started knifty knitting on the round looms. My husband bought me a book of patterns and after many hats and flowers and such I decided to start the panda bear pattern.
It says to use 2 strands as one when you cast on, do you continue to follow this through out the pattern? I have casted on, flat knitted and got confused when it told me to double wrap and knit.
Am I wrapping both strands as one, giving me 6 strands of yarn on the peg?

A double wrap would give you 4 strands probably. Does it say anywhere to drop one strand after you cast on? Sometimes you use yarn doubled to make an edge firmer and more sturdy, but mostly it’s doubled to make an item extra thick.
