thumb gusset

I'm trying to knit my first wristlet and I'm lost. I was ok until I bo on the wristlet part. I was able to arrange the thumb stitches from the stitch holder to 3 dpns. Now I'm stuck....

The pattern continues: Rejoin yarn at thumb opening, k11, pick up and k 2 sts

How do i rejoin the yarn? I know how to join yarn but how do i re-join yarn. Was I supposed to leave a bigger tail from the bo to rejoin? Or do I join from the skein?

Do I k11 then pick up 2 and then join the dpns? Do i pick up 2 then k11 then join the dpns? Or don't I join at all? I've never knitted from dpns without joining

Where do I pick up the 2 stitches? I am soooooooooooooooooo confused.

I hope this makes sense. Can I post an image of my thumb hole? Is the IMG tag allowed?

I would appreciate any help you could offer. Thank you in advance!
