Thick silk curtains (need to be re-lined) (Hove Green BN3)

Hello, I have some wonderful quality silk curtains with thick lining to give away. They belonged to my grandma and are probably about 50 years old! The lining is very worn/torn so they would either need to be re-lined or the fabric could be repurposed. I have four curtains in total, two measure about 220cm length x 100cm width at the top (across the pleats). The bottom of these two curtains measure approx 225cm width.
The other two curtains are slightly smaller, they measure approx 160cm length x 90cm at the top. The bottom width of these two curtains is also about 225cm width.
