Once you have visited the Brownie Goose shop and bought your Tilly pattern- Trace and cut pattern per instructions. Follow the construction steps laid out by the fabulous Amy of Brownie Goose until the part where you make a notch for the open back on page 6 (at least page 6 of the version available at the time of this posting)- just omit this. You then follow along with Amy’s awesome instructions until page 8- sew along her purple lines everywhere but the very bottom- don’t sew along this line:
The back piece should be completely open from side to side. Skip over the rest of page 9 except for clipping your seams. Then turn right side out and finish the armhole seams per instructions. It should be finished but open across the bottom from side to side at this point…note my arm holes are not finished on the picture below because I was attaching a sleeve to this one... more on that to come in a future post...
I then lay it out flat- right side out with the back pieces facing up and line up where the back pieces should overlap. Then topstitch around the back to attach the two pieces together. You can add your buttons at this point, or wait until you are done attaching the skirt (which is probably easier)- totally up to you.
I then run a gathering stitch across the top of both sides of the skirt and gather to fit my completed bodice. I leave my bodice right side out and flip my skirt wrong side out and slide the bodice down into it to pin it. I always do a sanity check and flip my skirt down to make sure I have it attached properly- not that I have ever attached one backwards. ; )
I then go back and serge my skirt/bodice seam, press upward and topstitch and that beauty is done! That is unless you need to go attach a fabulous button (I might have a special love for big buttons)! Enjoy your completely closed back Tilly top or dress!
