I would highly recommend using as large of a table for cutting as possible. I used to just lay fabric out on the floor to cut, but that is a huge pain--mostly for your back!
I ended up doing two things to stabilize and secure the edges. After cutting out all of the pieces, I fused very thin interfacing strips along every cut edge. This worked wonderfully to prevent the fabric from becoming pulled out of shape, and it kept the fraying to a minimum while I was working with it.
Here you can see how different the fabric looks after pressing, compared to unpressed. It was extremely shiny after pressing. Because of that, I did as little pressing of the finished garment that I could.
The other finishing technique I used was to cover all the raw edges inside with bias tape. This makes the inside look very clean and neat, and it prevents any sort of fraying. The only drawback is that the already somewhat bulky seams are now bulkier. Surprisingly, it's not visibly noticeable, only when you're wearing it do you notice.
My other tip for the day is: follow directions and stay-stitch the neckline! I don't know about you, but I always skipped stay-stitching. It seems like such a worthless step if you're going to sew it anyway, right? Well, remember my stretched out/wonky neckline on the brown version of this? I did not change the pattern at all, I just stay-stiched it and my neckline came out perfect. Live and learn!
