Hello! It took me a while to find this thread - I'm so glad it's still going. 
I'm amazed you've got a skirt done already, doyou - wow! That is inspiring.
I was going to post a separate thread here, but I'm guessing this is where we're chatting about projects?
I have a dilemma. There's a dress I really want to make, and a friend of mine is going to help me if I need it. The pattern is meant to be reasonably easy (there's a more complicated version with sleeves if I get ambitious later on!). However. The instructions say you need reasonably heavy-weigh cotton and to 'avoid quilting or shirting cotton like the plague'. Ok, fine. But, looking around on the net, the people who've made this dress seem often to have used cottons I've seen on quilting websites (Michael Miller, for example). And I know myself that quilting cottons vary quite a bit in terms of weight.
Should I risk it? I just don't see the point making a dress in a fabric I'm so-so about, and I have really looked pretty hard for nice heavy-weight fabrics.
FWIW, pattern is here: shop.byhandlondon.com/product/elisalex-dress
And the lass on this blog has made about 90 zillion versions in quilting cottons, and I think they look great: dollyclackett.blogspot.co.uk/2013/03/pensioners-tired-of-crows-stealing-your.html
I know this fabric (I've got another dress in it and I've got a bit in my stash), and it's heavier than some quilting fabrics.
I think I'm basically just looking for a bit of reassurance ... and possibly being a bit reluctant to step out of my comfort zone, because I know how these fabrics handle!
