Textile Centre say they are happy to supply half metres and to order you should just put in the next whole number but, unless they are telepathic, how will they know to supply and charge you for the smaller amount? Am I being thick?
"Price is for 1 metre (after one metre, fabric comes in one continuous length)"
"Please note that we are happy to sell half metres, as long as the minimum length is 1 metre (we will not sell less than 1 metre).
To do this, please order the next metre above what you want (e.g. order 2 metres if you want 1.5 metres) - this ensures that we still have quantity remaining that we can re-list when a listing has run its course. "
