Yes, there is enough room on the wooden blinds to allow you to trim up to 3" off each side. Although this is possible we do not recommend this as the wood may crack or splinter. We cannot accept returns on any blinds that have been modified or trimmed in any way.
Please note that you need to extreme take care when cutting the blinds to ensure that you do not cause injury to yourself, and also that you do not damage the blind.
If you need a bespoke sized wooden blind then we offer a made to measure blind service to save you the time and hassle of cutting your own blinds, all available at a great value price.
