#pattern help

Am trying to help a friend find it. She loves this hat and wants to make her own as she found this one in a thrift store.

The hat is worked in the round and the scarf is attached to it pretty seamlessly.

I am attempting to make a pair of gloves(this pair if you are truly curious), and I've come across an abbreviation the pattern and Google provides no explaination for:

It asks me to "Divide sts as follows" and then gives the abbreviation N1/N2/N3

I will do my best to help!!

I know this is a one color square but for the purpose of clarity- I did a color change

...

After fastening off at the end of row 3, it wants you to join at one of the triple crochets that separates the chain spaces

"working *behind* the third row"

(I would just flip it around)

"chain 5, slip stitch in next triple crochet. Repeat 8 times ending with a slip stitch at the beginning of the row"

(Slip stitch the ch 5s to each Triple Crochet)

You should have a row of loops on the *wrong side* of the square, parallel to the petals

I found a pattern which is the right size but I'm having trouble reading it:

1. MR with 6 SC (6)

2. INC x 6 (12)

3-4. (SC 12) x 2 RNDS (12)

5. CH 3, SC 16 (16)

6.

a. SLST 2 *SLST through both sides of the thumb

b. (SC 2, INV DEC) x 3

Do you know how I'd form the ch3 (should I skip stitches or not)? The pattern is this one:

And I NEED IT. As in I need to make it. But I’m coming up blank on patterns. It’s a shirt dress, cut on the bias, probably made of linen. It looks super flattering and comfortable: A+ for Emma.
