Hello,
Many thanks for your email,
The blinds we provide with the ability for a bottom up control are the perfect fit blinds- https://www.blindsbypost.co.uk/perfect-fit-blinds/perfect-fit-pleated-blinds
These are not available in a voile material but are available in a light filtering pleated fabric, wooden venetian or metal ventian,
You would just have to check per our measuring guide i the blinds are compatible with your windows first- https://www.blindsbypost.co.uk/measuring-guides#perfect-fit-blind
