Don't freak out. I'm not really going to wear a vintage bedsheet. It's a muslin.
I spent about four hours drafting, sewing, adjusting, marking, recutting and resewing [ad nauseum] a muslin for Butterick 5147, as my participation in Elizabeth's sew-along. Thank goodness this pattern only has two pieces. Without a dress form or a helper, it's pretty fiddly trying to make a pattern fit my non-standard body. I mean, what's with all the bust darts I seem to need? The pattern has two, but I added another two (from the armscye and neckline) to get it to sit right, so I've ended up with this starburst (hah, I first typed 'starbust') of darts, pointing to my nipple. Wtf? And when all's said and done, I'm unconvinced that a sheath dress, even one that is contoured correctly for my body, is going to be flattering.
But I will persist. I have a brown floral linen blend that I've been saving for a dress, so having got this far, I'll see it through. I even plan to insert my very first invisible zipper. Stay tuned!
