Hopefully I didn't just miss this in the description, but are the fabric requirements the same for 45" and for 54"? I'm making a size 8 or 10 (haven't decided yet). I want to make it out of free spirit voile and that stuff gets pricey so I'm trying to determine the bare minimum :) Or does anyone have a less pricey fabric suggestion for lining a voile. I saw batiste and lawn (and voile) mentioned in previous discussion. Can I get away with the cheapy stuff on the inside without ruining the comfort and effect of the quality stuff on the outside?
