I think if all you're cutting with your Accuquilt is 2" strips, you'll probably be fine. I don't have much waste with my Go Baby as long as they're straight cuts or simple shapes. However, once I get into curves, like an apple core or clamshell, there's plenty of waste. (Although I did take the waste pieces from the clamshell and turned them into leaves. Design opportunity!!
)
I will say that I don't often buy kits, so I can't speak to that. Connecting Threads IS generous in their fabric cuts.
