It's been a long time since I have done much garment construction, adult or child, & I think my skills are a little rusty. Having raised two daughters (& a son), I made lots of clothing for them as they grew up. Seems like every time I turned around, somebody needed a new outfit. Of course, Halloween was the best, but that's post for another day.
This pattern uses a purchased sweatshirt. You cut the bottom off, add a ruffle & trim to the remaining top to make the jacket, then turn the bottom of the sweatshirt upside down, insert elastic into the ribbing to use as a waistband & add another ruffle & more trim to finish it. I think it turned out pretty well, but I did find it's not as easy to sew for a child when you don't have any of their clothing for comparison on size. I intend to make another similar one for her in black & pink. Hopefully, the fit will be a little closer.
Okay, here's your mission, should you decide to accept it...pull out at least one project that you've been procrastinating about &, if you can't finish it, at least do a little work on it. You will have a wonderful sense of accomplishment for at least having tried & you will be that much closer to completion.
Keep on stitchin'
