These are great cushions for children to sit on, i have been making them for everyone and all from just 1 metre of fabric. This allows you to buy something really nice that you may not be sure of what to use it for. I also find they make nice footstools although my daughter is forever telling me to get off hers. I am going to make one that is a little bit taller just for my feet.
for instructions on how to make it. piping also makes things look more professional.
