Sometimes, the cure for a multi-month, multi-layer, high-stress, nitpicky-detailed historic sewing project...
Is a 1960's "Jiffy" wrap dress.
I mean, it wasn't literally a three hour project like it said it would be - but I had to take the pattern up from a size XS to (using my handy sloper!) the far end of the Large size. And then I altered it because hook and eyes? Please. It's got a long buttonhole in the right side body, and the ties are extra long to wrap around and through. Pictures later.
I may make a few of these... it's pretty nice really.
