I have done the samething using laquer thinner instead of alcohol, but I still perfer using rubber cement to attach the paper templates. I do my cutting in multiple locations and I never have to worry about rubbing the lines off or being too light to see. Also I found I find I make few mistakes in the final sanding by having the paper glued on the piece. The templates are easy to remove and occasionally will release themselves after they have set awhile. I do cut the wing ribs in pairs so I only need one template per set.
