Mostly I do what I call "organized scrappy" quilts. I've tried the pulling random fabrics out of the bag thing, but that doesn't work well for me! :D I'm more likely to plan it out on my design wall so I can see how I like the play of colors, values and patterns next to each other. It's a bit more work, but that's what works for me. :D
Oh, and congrats on the baby!!
