Luckily the braiding which the tassels sit under, lifts up on one side which means with a good pair of scissors the tassels can be removed with ease.
So on today's 'to-do' list, i will be removing the said tassels. and fear not, those redundant tassels will be recycled to make some hair barrettes, and other lovely leather accessories, which in turn will hopefully refund me the cost of the leather jacket.
