I prepared green binding for a crib sized quilt also I made brown and white binding for a lap sized quilt.
When selecting fabric for my quilt projects, I try to buy my binding at the same time. I cut the strips right away, because, I don’t want to use if for a project it wasn’t intended for and then be disappointed when the top is quilted and ready to be bound but I can’t find my binding fabric.
Having my binding prepared is convenient. I also saved time by repeating the process and making two sets of during one sewing session.
