These Bobinette Geometri curtains from 1960 are amongst my favorite Panton curtains. They are not easy to find and are often expensive if they come up. 

I try to find enough of them to cover a 950 cm long window in the new house. This pair have a width of 320 cm together and with 4 other curtains I already have, I come up in a width of 860 cm. If you have one or two more, please let me know.
