I promised I show y'all how I did my "cheater" FBA on the Jalie 2794 Sweetheart top, and also how I did the double band neckline finish. Well, let's make it happen!
Let's start with the FBA. For knit tops, I find the easiest way to do an FBA is to blend the sizes of the front pattern piece at the underarm, and then just ease the excess side seam length into the back. It's easy and it works well. Here is how I usually do it. With the Sweetheart Top, the bodice front is in two pieces, right at the underarm, so I had to modify the FBA a little bit.
Now, how about that double band?
Sewing for Children book. This whole series is wonderful, although most of the pictures are quite dated, and you have to really look past the bright 80s colors and styles to get to the meat. It's well worth the effort though.
Your garment - In my mockup, we'll pretend the pink piece is my garment
Two bands, cut to the length specified by your pattern, with one band the width your pattern specifies, and the other 1/4 to 1/2 inch more narrow. The more width you take off, the narrower your inner band will be and the more of your outer band will show. In the sample, the stripe is about 1/4 inch more narrow than the solid blue.
I think this technique has a lot of potential, and not just in children's wear. I hope it has given you something to think about. Now, get those machines humming!
