: I have the cloth and the rotary cutter, but i remember reading here someone's
: post of using bias cut strips for this and the pulled on the strips as the
: applied them and the turned out 'white' in spots. The thread went along
: the lines that he had stretched the weave too tight and it did not wet out
: clear. The thread just petered out after that. So I have left this idea
: hanging. I have 3" 9oz tape too, but only planned to use this in the
: inside seam. What is best glass to use for the outside seam anyway ????

I don't profess to be an authority on the subject, but I've used bias cut cloth to reinforce the stem and stern and although it does stretch and narrow a bit, it still wets out nicely. I recall chatting with a guy at the Newfound Rendezvous who said he used 9 oz tape on the exterior seam of his Night Heron and just couldn't get the tape to disappear. He ended up sanding off the whole mess and cutting his own strips of cloth tape.
As for the "white spots on bias strips' thread, it sounds like it may have been unrelated to the fact that it was bias tape.
