I have this book and it's really great: From Marti Michell: Machine Quilting in Sections book

Also, you might want to think about making rag quilts: How to Make a Rag Quilt (Start to Finish Instructions)

There's also quilt as you go: https://www.google.com/?gws_rd=ssl#q=quilt+as+you+go

Our ancestors did not have machines with big throat spaces and they made beautiful quilts.

Just don't stress.
