This poncho is very easy to make. Made this one for my 12 year old grandson. He wears a size 14-16 in boys. I made this one to fit a little bit large so it should also fit a small adult.
For the finished product I used worsted weight
yarn and a size J (6mm) crochet hook.

For border, 2 rounds of sc in each stitch. Fasten off. Weave in ends.
Attach fringe. Cut strips of yarn twice the amount of desired length. Fold in half. Insert hook from front to back ( both loops of ending round), pull loop through, catch strands with hook and pull through loop. I used 1 strand about 7 inches long in each stitch. If you desire a fuller or longer fringe, use 2 strands, cut to desired length.
This pattern can be easily adjusted or size. When adding chains to beginning chain, make sure the number of chains is in multiples of 4, so you can divide evenly for each of the 4 sides. It is also a good project for using remnant yarn.
