The motor is within the tube of the blind one end will have the motor end on which allows you to plug in the charger to charger the blind.
You can have the fabric rolling from either the front of the blind (reverse roll) or the back of the blind (standard roll),
The bottom bar we use a no sewn bottom bar, this gives the roller blind a much better look aesthetically as the face of the fabric is wrapped around the bar rather than an unsightly stitch line, the back of the bottom bar is always uncovered (facing the window) and is white in color
I hope this helps, If any further questions please do get back in touch.
