...well, we know lots of sewers who love to do what's called 'tissue fiting', and if you're one of them, and you get great results, we say, do whatever works for you!...
...'tissue fitting' means that you pin together the tissue or paper pattern and fit that on your dressform...
...but we have to say, in all honesty, that we're not really feeling the love for this method...
...why? because paper or tissue just doesn't behave in the same way as fabric! you'll get a *rough idea* of the fit, but if you want a great fit (instead of a good-enough fit) then it's a muslin you need!...
