i cut 32 pieces of random fabric left overs. each piece is 5 X 5cm
you can make it bigger or smaller (depends on how much left overs you've got) :P
now pin 16 pieces together and sew
this is how it would look like after sewing , make 2 of these
pin the 2 pieces (right sides together) and sew
leave an open end to turn your scarf right sides out
fold the edges in and pin
top stitch the entire scarf, closing the open end as you go ...
and you're done.
