another thing to take into consideration.. if its over stretched to the point of nearly tearing- dont over stretch it as it can go out of shape
the method everyone will use something different - but getting the calico part center (holds the bows) is so important
If you dont center the calico on the bow you be waiting till the cows come home, then you can follow with your eye the shape - you dont even have to have it clamped down just follow the curves with your finger
If it curves around then you know it will work if you have it pulled into shape with equal force from each side
yes i would take the sides / back down to check and possibly re position
you always fit the wires in the center first - thats how i do it and i would imagine most would
wires because they are fixed.. the headlining wont move once the tabs are bent over.. so start there making sure equal amount of calico each side, then go either forward or back.. either way the center section wont move as tabs are holding
you should be able to pull the headlining at the front of the car in the middle with 2 fingers to see how the curve is
different material also varies the fitting - velour easiest by far to fit..it stretches - the herringbone ribbed can be slightly easier also.. a material with no stretch at all makes you work to fit it
