Please help ~ increase 8 st on each side~

(sorry I posted this first in the general)
I am new in the forum

I want to make those little cute sweaters for ornaments or baby gift tags. and I’ve been looking trought the treads, trying to find a clue on how to increase 8 stitches on both sides
(like to make a T shape), but didn’t find anything

I only know how to increase from the front and back loop of a stitch, but is not working, since I need 8 st on each side
could some one help me on this one?

You don’t actually increase that many sts, but CO the 8 sts. sue
