I know there is some debate about whether you still need to pre-wash cotton fabrics before you sew them up these days, but I still like to.  For one thing, I have no idea what the conditions on the factory floor were like, or what the fabrics were exposed to in shipping!  And it can’t hurt to make doubly certain that no unwanted shrinkage will occur. In my machine are a beautiful monochromatic ’50s floral from Nana’s stash that reminds me of charcoal sketching, and a sweet pink and green and yellow ’30sish number and a sassy yellow and grey and white 30ish number, both from reproductionfabrics.com. I say ’30sish, because (to the best of my knowledge) most prints from reproductionfabrics.com aren’t perfect reproductions, but modern prints that match the aesthetic of the era.  Still lovely, but not exact matches.
