Last week I needed to create a birthday gift and so I decided to spray dye a pull tied bag as a WIP bag for socks :)
To dye this bag I needed:
A cotton pull tie bag, washed
Fashion spray - fabric spray dye
some cardboard to place inside the bag
a covered surface
Place the cardboard inside the bag, and the stencil on top of the bag where you would like to see the pattern on the finished product.
Go wild :)
Allow to dry and then iron underneath a cotton cloth to fix the colours!
