Mentally I'm already in Columbia and it shows in my sewing. I'm shocked at how successful this project was considering my logic was: cut one piece at a time and see how much detail you can add before you run out of fabric.
I. First I cut my main pieces (I used up pretty much every square inch of my 1 meter piece of fabric, so I first wanted to make sure I had enough for these. Im a EU36/US4. Identical 2 front pieces and two rectangles to create the tied-up bow part.
III. Then I made two shoulder straps (which I had to make out of 2 pieces each, since at this point I was working with scraps), and attached them to one of my front pieces.
V. Then I cut 4 little rectangles, about 8 cm wide each, to attach extension pieces to the sides of each front piece.
And placed the completed front pieces right sides facing, pinning the neckline, and sewing. I sewed the neckline V twice, adjusting it a bit deeper than I had originally cut it. I also always sew over the shoulder straps a couple times to reinforce them. Then just clipped the bottom of the V and all corners, and turned right side out.
VI. Last bit was the back. I took my elastic and measured how wide I'd need to sew the casing. Sewed two of them (for my size, for an about 30 cm long piece of elastic). And slipped my elastic pieces in their casings.
Then I pinned the ends of the elastics to the edge of one side of the back of the top. If you want the criss-cross style I did, you need to pin them at an angle. Sewed in place, and then folded the lining side of the front piece over, sandwiching the straps in between.
I tried the top on to confirm how long the back straps needed to be, and then attached them to the other side. After that, I knew it was coming - the fit wasn't good due to the elastic crumpling the sides. I contemplated for a while putting something in to act as bones and keep things flat, but then I realized I could just do darts.
