first go to your local pound shop or other discount place and purchase 2 cotton rugs
fold one in half and cut a 3 inch slit from the edge towards the centre
once you have done this, depending on the type of rug you have, you'll need to stop it fraying, the kind of rug i have was easy, just pull a few strands to make it fray on purpose, then tie off the vertical threads you have poking from the top of the fabric. other kinds of rugs may need sewing or if you are lucky, you may be able to glue them.
repeat on the other rug, making sure your neck hole is level on both pieces
sew the edges that will form the back of the poncho together, don't sew it too tightly or the seam will be too stiff.
now the front is slightly trickier, but not much!
you'll need a safety pin for this bit, put the poncho on (if it's for you, you may need some help) pin the two edges of the poncho together where you think it needs to be so it's big enough to get on and off easily,
take the poncho back off with the pin still in place, and sew from the bottom edge to where the pin is, this will leave you with a roughly triangular shaped hole for your head,
now if you want to take your time and put in some effort, you can trim the excess from the corners and stitch the neck, or if you are like me and just a little lazy, just fold them over and use one strong stitch in the point of the triangle.
and that's about it!

and here it is......
