There are many variables that go into choosing batting. Do you want to show off the top (select a thin batting), or would you prefer to show off the quilting (thick is what you want)?
How will the quilt be used? Fiber content will greatly affect how the quilt looks after laundering and how well the batting holds up through frequent washings.
Will you be hand quilting or machine quilting? Your needle will move more easily through some fibers than others – an important consideration for hand quilting.
