woven interfacing is fine to use...the difference in woven & non-woven is the fiber- woven is more like a fabric- non-woven is more like a soft paper- non-woven tears easily- woven does not-
you can use which ever one you have & want to use. (do check your iron setting- the woven *might* shrink a little with too much heat- you could use a press cloth to protect it) i tend to always use woven fusable interfacing- i just like to work with it better than the non-wovens. tricot is nice too- but if you already have the woven there is no reason to go buy something different
