Two bolts of yukata fabric & yukata obi

Decluttering my parents' home.
This was purchased by my mother, who is now 91, with the intention of making something herself, so I believe it has been stored for quite some time.
It seems to have been carefully stored and there are no noticeable stains, but as it is a long-term home storage item, I have set a low price.

Regarding the obi...
I'm not sure if you can tell from the photos...
It has a lovely pattern... and the reverse side shows the weaving threads
(Photos 9 & 10)
My mother says it can be folded in half and used as a half-width obi as is, but I'm not sure myself.
m(_ _)m Perhaps the buyer will understand better...
Please only purchase if you understand that this is a long-term home storage item...
and that there may be something I have overlooked.
Thank you.
