How to decrease and close crown of hat?

I am following the instructions in the Loom Knitting Primer for the Garter Stitch Hat and now that I am at the part where I decrease and close the crown I am very confused! It says,

"Divide the stitches on the loom into 4 groups of 9 stitches. Each group will be worked separately.

Row 1: Move the first stitch at the end of this wedge over to the 2nd peg. Knit all the stitches. Knit 2 oever 1 on the end pegs.

Row 2: Purl. Repeat rows 1-2 until you have only 1 stitch left ont he wedge. Break yarn leaving a 14 in tail. Place the last stitch remaining from the wedge on a stitch holder. Attach yarn at the first peg of the next wedge to be worked and repeat wedge instructions."

CAN ANYBODY TELL ME WHAT THEY MEAN BY “WEDGE?” Also, “Knit 2 over 1 on the end pegs?” If someone could better explain this in new knitter terms that would be great! Thanks so much! I REALLY want to complete my hat! :slight_smile:

Maybe ‘wedge’ means section? I think you’re going to do something like ‘knit 2 together’ in hand knitting; lift one stitch over another.
