Instead of getting rid of old curtains it can be a good opportunity to re-cycle them, incorporating them into the colour scheme of another room (cushions!), or remaking them as blinds, giving you the option of changing more than one room without the additional expense!
Contract work: A customer approached me to help furnish a conference facility. I was commissioned to make curtains and voiles for the 42 bedroom hotel together with dressing the stunning garden and drawing rooms in this mid-victorian mansion. All in 8 weeks!
