Here is my version of the smocked sundress:
I was convinced I did something wrong. So off to my best friend the google bar.... Hmmmm.
I found a website that suggested winding the thread tighter around the bobbin and lengthen the stitch length. Wow, that made a difference. But still not enough smocking for my 15 months old waist. So I ended up tighten the elastic by hand. I guess not the proper way to do it but hey it worked. So after that was done the dress came together pretty easily.
Next off I tried my version of the Ruby's Bloomers. After the experience with the sundress I did the same with the elastic in the leg openings. Tightened it by hand. Well here is the result:
And here are some action shots of both.
But all in all I think the experience with the elastic thread was definitely a learning experience and so worth it.
