I didn't make a swatch, by my bag is coming out "roomy". So it might not be a bad idea if you don't want a "roomy" bag!
I've never done Icord either, but I have pieced together bags before! So we can figue the I-cord out together!
Just think, what a cool diaper bag it'd make, all home made and wonderful!
ETA: and Rebecca...lol..why not today?
